Title: Using Computer Algebra Systems to Test and Improve Mathematical Theory

Abstract: I will show examples of how I use Computer Algebra Systems (Macaulay2, Singular, and Magma) to try to understand mathematical theory, test it, and improve it. These examples may be about integral closures of rings or ideals, or desingularization of function fields, but the takeaway is how completely understanding small but non-trivial examples is important in shaping theory.

Title: Matrix decompositions and canonical forms

Abstract: The problem of writing a matrix into a product (or sum) of special types is at the core of linear algebra and matrix theory. We look at classical decompositions and give more general factorizations using the theory of canonical forms and other techniques in matrix analysis.

Title: Dynamics in chemotaxis models of parabolic-elliptic type on bounded heterogeneous environments

Abstract: In this talk, I will first derive briefly chemotaxis models, point out their importance, interesting dynamical questions related to chemotaxis models and some of the existing works. Next I will present some of our results on dynamics of one-species chemotaxis models of parabolic-elliptic type in heterogeneous environments. First, we will discuss our result on local existence and uniqueness of solutions.

Next, the result on boundedness and global existence of solutions which is proved under some natural parameter regions. Then the result on the existence of a positive entire solution which is proved under the same parameter regions of global existence. Finally, the result on uniqueness and nonlinear stability of positive entire solutions which is proved under some further parameter regions.

Title: Applications of nonautonomous and random dynamical systems in the applied sciences

Abstract: In this talk I will introduce several mathematical models for different applications in biology, ecology, and chemical engineering. The common character of these models lies in that the forcing depends on time, and thus gives rise to a nonautonomous dynamical system or random dynamical system. Basic techniques to analyze and simulate such systems will be introduced.
