The interactions of cancer cell with the environment play an important role in cancer cells migration and the formation of secondary tumors. In this talk, I will present a discrete model, motivated by these cancer cell interactions, to gain further...

Transitional phenomena are ubiquitous in fluid dynamics and other nonlinear systems; they occur whenever there are multiple states in which a system can reside. Frequently, we are able to investigate when and how a system transitions from one state...

It is well known that the prime numbers are equidistributed in arithmetic progression. Such a phenomenon is also observed more generally for a class of multiplicative functions. We derive some variants of such results and give an application to...

We introduce an efficient algorithm, called partition of unity extension or PUX, to construct an extension of desired regularity of a function given on a complex multiply connected domain in $2D$.Function extension plays a fundamental role in...

The mod $p$ Steenrod algebra is the (Hopf) algebra of stable operations on mod $p$ cohomology, and in part measures the subtle behavior of $p$-local homotopy theory (as opposed rational homotopy theory, which is much simpler). A classical theorem of...

B cells integrate signals from multiple activating and inhibitory receptors in a highly regulated spatiotemporal manner to regulate B cell receptor (BCR) signaling and B cell activation. Marginal Zone (MZ) B cells are unique subset of B cells that...

The Corradi-Hajnal Theorem gives a minimum-degree condition for the existence of a given number of vertex-disjoint cycles in a simple graph. We discuss a number of variations on the Corradi-Hajnal Theorem, changing both the nature of the necessary...

Solutions to the classical Weyl problem by Nirenberg and Pogorelov play fundamental role in the notion of quasi local masses and positive quasi local mass theorems in general relativity. An interesting question in differential geometry is whether one...

In this talk we report on some research projects from summer 2017 supported by NSERC-USRA. In the first part of the project, we surveyed all existing explicit results from the past 60 years on prime counting functions, with a special focus on theta(x...
