报告摘要1Abstract.We will illustrate aclassical problem, that is the solution, by the double-layerpotential method, of the Dirichlet and Neumann problems for a domain in Rn+1.When  is a bounded, regular, open set, say C1+_class for some_ > 0;the operator studiedis compact, so Fredholm theory allows one to solve the problem. When is just of class C1,or of class Lipschitz, the operator is a singular integral.Calder_on's research programme was to solve this problem. In thistalk, we describe how this problem was solved by Calder_on, Coifman,McIntosh, Meyer, Verchota, Dalhberg and Kenig.

报告摘要2

In this talk we start with a basic formulation for two-fluid gas-liquid flow. In order to
motivate for further work on mathematical analysis of the compressible two-fluid model,we briefly discuss four different applications of the two-fluid model:
two examples from fluid mechanics and two examples from life science (study of living organisms).
