My research interests and
activities include various areas of non-Archimedean Analysis: one-variable and
multi-variable calculus, power series and analytic functions, measure theory
and integration, optimization, existence and uniqueness of solutions of
differential equations, complex analysis, and functional analysis over
non-Archimedean valued fields. The focus of my research has been on the
Levi-Civita fields which were first introduced by the Italian mathematician
Tullio Levi-Civita at the end of the nineteenth century. Of those Levi-Civita
fields, one (which we denote by R) is of particular interest; it is
shown to be the smallest non-Archimedean ordered field extension of the real
numbers that is complete in the topology induced by the order and real closed.
In fact, R is small enough so that the numbers
of the field can be implemented on a computer; and this allows for many useful
applications, one of which is the fast and accurate computation of the
derivatives of real-valued functions up to high orders.
We have studied in my
research group two topologies on R: the valuation topology induced by
the order on the field, and another weaker topology induced by a family of
semi-norms, which we call weak topology. We showed that each of the two
topologies results from a metric on R, that the valuation topology is not
a vector topology while the weak topology is, and that R is complete in the valuation topology while it is not in the weak
topology. Then we studied the properties of both topologies in detail; in
particular, we gave simple characterizations of open, closed, and compact sets
in both topologies. Finally, we showed that the metric which induces the weak
topology is translation invariant.
We studied convergence of
sequences and series in both topologies mentioned above, which led to an
exhaustive study of power series. A handful of people had investigated power
series on the Levi-Civita fields before, but all the previous studies had been
restricted to the special case of power series with real coefficients. We
dropped that restriction and showed that power series on the Levi-Civita fields
have all the nice smoothness properties that real power series have. In
particular, they satisfy the intermediate value theorem, the extreme value
theorem, the mean value theorem and the inverse function theorem; they are
infinitely often differentiable; and they are re-expandable around any point
within their domain of convergence.
While it is a known fact
that conventional continuity or differentiability are not sufficient to
guarantee that a function on a closed interval of a non-Archimedean ordered
field be bounded or satisfy any of the common theorems of real calculus, we
have shown that under mild conditions, differentiability is sufficient for the
function to assume all intermediate values and a differentiable inverse
function. We also showed that conventional differentiability is not the right
one to study optimization questions on non-Archimedean fields in general; and
based on a stronger concept of differentiability, we studied finite-dimensional
optimization both with and without constraints. In both cases, we derived
necessary and sufficient conditions of first and second order for a function to
have a local minimum at a point of its domain.
We developed a measure
theory and integration on the Levi-Civita field R. We
introduced a measure that proved to be a natural generalization of the Lebesgue
measure on the field of the real numbers and have similar properties. Then we
introduced a family of simple functions from which we obtained a larger family
of measurable functions and derived a simple characterization of such
functions. We studied the properties of measurable functions, we showed how to
integrate them over measurable sets, and we showed that the resulting integral
satisfies similar properties to those of the Lebesgue integral of Real
Analysis. We generalized the results to two and three dimensions. In
particular, we defined a Lebesgue-like measure on R2 (resp. R3). Then we defined measurable
functions on measurable sets using analytic functions in two (resp. three)
variables and showed how to integrate those measurable functions using iterated
integration. The resulting double (resp. triple) integral satisfies similar
properties to those of the single integral as well as those properties
satisfied by the double and triple integrals of real calculus.
Together with my collaborators Jose Aguayo and Miguel
Nova from Concepcion (Chile), we developed an operator theory on the Banach
space c0 over C:=R+iR, where c0 denotes the space of all null sequences of elements
of C. The natural inner
product on c0 induces the
sup-norm of c0. We showed
that c0 is not
orthomodular; then we characterized those closed subspaces of c0 with an orthonormal
complement with respect to the inner product. Such a subspace, together with
its orthonormal complement, defines a special kind of projection, the so-called
normal projection. We presented a characterization of such normal projections
as well as a characterization of other kinds of operators, the self-adjoint and
compact operators on c0.
Then we worked on some B*-algebras of operators, including those mentioned
above; we studied normal and Hilbert-Schmidt operators; and finally, we studied
the properties of positive operators, which we then used to introduce a partial
order on the B*-algebra of compact and self-adjoint operators on c0 and studied the properties
of that partial order.
While the Levi-Civita field R is interesting to study in detail for the
reasons stated above, I have also expanded my research focus to include any
non-Archimedean field extension of the real numbers that is real closed and
complete in the topology induced by the order and whose Hahn group is
Archimedean; such a field is denoted by F.
For example, we studied the properties of weakly locally uniformly
differentiable functions at a point or on an open subset of F or Fn
and we proved local versions of the intermediate value theorem, the mean value
theorem and Taylor's theorem for weakly locally uniformly differentiable
functions on F. We also proved the
inverse function theorem and implicit function theorem for weakly locally
uniformly differentiable functions from Fn
to Fn and from Fn to Fm (m
< n), respectively. Moreover, the work on the topological structure as
well as on the integration theory and its applications on the Levi-Civita field
R has recently been extended to the field F.

As the Associate head for
Undergraduate Studies, I assisted the Department Head with all undergraduate
matters; for example, I chaired the Undergraduate Studies Committee (see
below), I decided on undergraduate students awards and I reviewed applications
for course credit transfers.
As the chair of the Undergraduate Studies Committee, formerly the
Curriculum Committee, (2011- 2021), I worked with other members of the
Committee on making necessary curriculum and course changes. Then I presented
those changes to COCAP for approval before being forwarded to the University
Senate. Our undergraduate programs underwent an external review in 2015, which
led to an overhaul of all honours and major programs:
· I
actively participated in preparing the report that was distributed to the
undergraduate program review committee prior to their visit as well as in
meetings with the review committee during the visit (March 2-4, 2015) and in
drafting the Department’s response to the review committee.
· Following the recommendations in the
report from the undergraduate review committee, I led the efforts in 2015-2017
of the Curriculum Committee and the Department on making major changes to our
undergraduate programs as well as the joint honours programs with Chemistry,
Computer Science and Mathematics. Then I presented the package of changes for
approval by COCAP (Faculty of Science Committee on Courses and Programs), then
by the Faculty Council and finally by SCCCC (the Senate Committee on Curriculum
and Course Changes). The changes were approved by all of the aforementioned
committees and they became effective as of the fall 2018 term.
Moreover,
as the chair of the Curriculum Committee, I coordinated the preparation at U of
M of the 2015 CAP University Prize exam (which was written throughout Canada on
Feb 3, 2015); and then I coordinated the grading of all written exams.
As the chair of the Honours/Majors Committee (2009-2015), I assigned a
mentor for each of the students in our undergraduate programs and I served as a
mentor myself for all the students in the Physics & Math Joint Honours
program. Moreover, I assisted the Department Head in selecting the qualified
students for the undergraduate awards.

administrative aspects of the institute, e.g.
· organizing
all WITP seminars at the University of Manitoba (8 to 10 per year);
· approving
all WITP expenses and balancing the budget;
· organizing
a WITP summer research symposium at the end of August at which undergraduate
and graduate students from the U of
Manitoba and U of Winnipeg
presented their work to other students and professors;
· preparing
the WITP annual report in December, which included all the research activities
of the WITP and its members (publications, talks, etc.);
· maintaining
the website of the WITP.
As the
Past Director of WITP, I was one of three judges selecting the best PhD thesis
in theoretical Physics for the DTP-WITP PhD Thesis Award; in 2017 there were 6
excellent submissions, totaling more than 1000 pages. Moreover, I was a
co-organizer of a two-day WITP summer research symposium on July 31 and August
1 (2017) at the University of Manitoba to which we invited three
well-established theoretical physicists and a mathematician (my collaborator
from the University of Concepcion in Chile) as guest speakers to give one or
two lectures each at the symposium.
As the
Director Elect of WITP (2013 and 2014), I worked with the Director (A. Frey-
University of Winnipeg) on preparing the 5-year review of WITP and on securing
a significant increase in funding for the institute from the three universities
in Manitoba (University of Manitoba, University of Winnipeg and Brandon
University).
