报告题目：数学与绘画美学中的奇异摄动

报告人：侯磊教授，上海大学数学系

报告摘要：Some interesting topics in the talk will be presented in natural and artificial solutions of mathematics and fine art for deformable contact materials. Convergence property of the random solutions will be discussed in this talk. High order finite element solution is given for the coupled equations on Gauss-Lobatto quadrature for contact surface.

Summary---Under the condition of high speed collision, the solid material can cause significant variation in such short time. Thus we can agree that it also has fluid property. In this talk, we try to use the fluid-structure coupling equations to describe the characters of complex contact surface. The equations could describe the large deformation problem of elasto-plastic material. The results could reflect the boundary layer phenomena of the stress change. They confirm with physical properties of complex contact surface. Because of the complexity of the nonlinear problem of viscoelastic fluid in the linear frame, the development has now been focusing on the mixed solution in nonlinear spaces.
