报告题目1Fast  and accurate numerical methods for subsurface flow and transport

王宏教授,长江学者,南卡罗来纳大学

报告摘要:In  this talk we go over fast and accurate numerical methods for the coupled system  of (integer-order) partial differential equations in subsurface flow and  transport.

 

报告题目2A fast finite volume method for a space-fractional  diffusion equation discretized on a locally refined mesh in the  plane

贾金红博士,山东师范大学

报告摘要:In  this work, we consider a boundary value problem involving Caputo derivatives  defined on the plane. Solutions to fractional diffusion equations may exhibit  boundary layer and poor regularity even if the diffusivity coefficient and  right-hand side are smooth. Numerical experiments defined on a uniform mesh has  been observed that the numerical solutions exist numerical oscillations around  the boundary layers. We develop a fast locally refined second-order finite  volume method for variable-coefficient, conservative space-fractional diffusion  equations in the plane to resolve boundary layers of the solutions.
