Distribution theory, generalized integral transforms in Banach spaces, and nonlinear fractional differential equations using fixed point theory.
Fractional calculus is the theory of integrals and derivatives of arbitrary order, which unifies and generalizes integer-order differentiation and n-fold integration. The beginning of fractional calculus is considered to be Leibniz’s letter to L’Hospital in 1695, where the notation for differentiation of non-integer orders was discussed. I am currently working on fractional calculus of distributions, the generalized fractional Laplacian, and nonlinear integral, differential and integro-differential equations using fixed point theory.
Algorithm analysis and data networking.
Current studies of messy broadcasting have so far concentrated on finding worst-case times. However, such worst-case scenarios are extremely unlikely to occur in general. Hence, finding average-case times for completing messy broadcasting in various network topologies is both necessary and meaningful in practice. The area of my research is focused on seeking the average messy broadcast times of networks such as hypercubes, d-ary trees and complete graphs using randomized algorithms and probability theory. Furthermore, the approach I introduced for average-case time complexity can also be used to simplify the proofs of existing results of worst-case situations.
I have worked at the University of Regina, University of Lethbridge, University New Brunswick, Cape Breton University, University of Alberta (Augustana)
before joining Brandon University in the summer of 2002, and have taught a wide range of courses from Mathematics to Computer Science. Here are the courses I have done in Brandon:
