Title: The covering method: an intuitive approach to the computation of p-divisibility of exponential sums Abstract:  Exponential sums over finite fields are an important tool for solving mathematical problems and have applications to many other areas. However, some of the methods and proofs of the results are non-elementary. The main purpose of this talk
Title: Phase field method for geometric moving interface problems and their numerical approximations Abstract: Â In this talk I shall first give a brief introduction to the phase field method for general geometric moving interface problems. The focus will be on presenting its idea, formulation,and relationship to other methods for moving interface problems such as the
