Title: Free boundary problems and discrete geometric flows

 

Abstract: What is the shortest path between two sets? Geometric analysis gives a way to describe such paths in terms of a partial differential equation. Approaching the shortest path by a gradient descent is difficult when faced with the subtle boundary condition that the endpoints of the curves must remain in the given sets, so I will describe a semi-discrete approach. Computer simulations and animations lead to some interesting conjectures.

Title: Wannabe homomorphisms avoiding arithmetic progressions 
 
 
Abstract: How large can a set of numbers be, without containing a triple of the form a,a+d,a+2d? I hope to take some suggestions from the audience and see where they lead.

Title: Even and Odd Decompositions of the Bernstein Polynomial Operators
 
 
Abstract: The Bernstein polynomial operator \(B_n\) maps a function \(f \in C[0,1]\) to a polynomial of  degree at most \(n\). Here, the purpose is to investigate the approximation of even or odd  functions in \(C[-1,1]\), by constructing operators based upon the Bernstein operators which preserve evenness or oddness. This can be done in more than one way. Two methods will be considered in some detail.

Title:  Disk configuration spaces and routing numbers of graphs
 
Abstract: Configuration spaces of disks in a region of the plane produce rich topological questions.  We'll focus on a discrete version of the problem of estimating the diameters of these configuration spaces.  This combinatorics problem was solved in joint work with undergraduate research students, but higher-dimensional extensions of the problem remain open.

Title: Statistical Sampling for Uncertainties in Partial Differential Equations & SIAM Student Chapter

 

Abstract: Statistical sampling is the process of selecting a subset from a population with the aim of estimating population-level properties. For uncertain natural or engineered systems governed by partial differential equations, sampling presents a computational bottleneck, since the per-sample cost is high. We discuss a few strategies for improving the sampling efficiency for both prediction and control of these systems.   I would also like to talk briefly about the SIAM Student Chapter at Auburn, its purpose, and our plans for the year.

Title: Dynamical Aspects in Chemotaxis Models



Abstract:   Chemotaxis models are used to describe the movements of biological species or living organisms in response to certain chemicals in their environments. The current talk is concerned with various dynamical aspects in chemotaxis models. In particular, I will discuss the finite-time blow-up prevention by logistic source in parabolic-elliptic chemotaxis models on bounded domains and the effect of chemotaxis sensitivity on the spatial spreading speeds of chemotaxis models with logistic source on the whole space. 

The talk is based on the joint works with our two former PhD students,  Tahir B. Issa and Rachidi B. Salako, and our current PhD students, Halil Kurt and Shuwen Xue.

Title: Equitable \((s,p)\)-edge-colorings of \(K_v\)

 

Abstract: This talk will focus on (not necessarily proper) \(s\)-edge-colorings of the complete graph, \(K_v\), in which, for each vertex the edges incident with the vertex are colored using exactly \(p\) colors.

In the spirit of proper edge-colorings, such \((s,p)\)-edge-colorings are required to be equitable: the edges at each vertex are shared evenly among \(p\) colors. Results obtained about the structure of these colorings will be discussed. The motivation behind this work will also be addressed, including a scheduling problem and extension to equitable \((s,p)\)-block-colorings of \(C_4\)-decompositions of \(K_v-F\), where \(F\) is a 1-factor of \(K_v\).

Title : Introduction to Functional Data Analysis 

 

Abstract: Due to rapid technological developments, we handle increasingly large and complex datasets, and further, monitoring devices are becoming even more sophisticated to produce statistical units sampled over finer and finer grids which result in massive continuous data. The generated data through these new technologies are called functional data. I will give an introduction to functional data analysis, explain what statistical problems are studied in this field, and talk about a few research problems that I am interested in.
