The closest point method (CPM) is a numerical method that was originally developed to solve partial differential equations (PDEs) on smooth, static surfaces using standard finite difference and interpolation methods. In this talk, we describe a...

In the first part of the talk we discuss a sum-product type result on points near the unit circle that are almost closed under additions. Later we apply the obtained result to establish several universal behavior of the roots of random eigenfunctions...

The dimension of a poset P is the minimum number of total orders whose intersection is P. We prove that the dimension of every poset whose comparability graph has maximum degree $\Delta$ is at most $\Delta log^{1+o(1)} \Delta$. This result improves...

Talk 1: Nilima Nigam- An overview of finite element methods à la Dominik Schoetzau Finite element methods occupy a central and ubiquitous place in much of modern engineering and scientific computing, to the point where they are now treated as 'black...

We will discuss Gradient flow structures in parabolic type PDEs and interface motions. Such structure introduces physical interpretations to time-dependent PDEs in terms of energy dissipation, and allows a weak notion of global-time solutions to...

Let k be a field, A be a finite-dimensional k-algebra (not necessarily commutative, associative or unital), and R be a commutative ring containing k. An R-algebra B is called an R-form of A if there exists a faithfully flat ring extension S/R such...

The celebrated Erdős-Pósa theorem states that every undirected graph that does not admit a family of k vertex-disjoint cycles contains a feedback vertex set (a set of vertices hitting all cycles in the graph) of size O(k log k). After being known for...

This weekend conference will bring together algebraic geometers of Western Canada in order to build and strengthen collaborations, disseminate research, and contribute to the training of students and postdoctoral fellows. Talks will be given by 8...

I will discuss how Steenrod operations on mod p Chow groups can be used to study problems in algebra and algebraic geometry. For quadratic forms, Steenrod squares on mod 2 Chow groups are used. Some of the problems that can be solved by studying...
