A NEW PSEUDOSPECTRAL METHOD ON QUADRILATERALS
《Journal of Computational Mathematics》2016年第4期365-384,共20页Benyu Guo Hongli Jia 
In this paper, we investigate a new pseudospectral method for mixed boundary value problems defined on quadrilaterals. We introduce a new Legendre-Gauss type interpolation and establish the basic approximation results...

Degenerate scale problem in antiplane elasticity or Laplace equation for contour shapes of triangles or quadrilaterals
《Applied Mathematics and Mechanics(English Edition)》2012年第4期525-538,共14页陈宜周 
This paper provides several solutions to the degenerate scale for the shapes of triangles or quadrilaterals in an exterior boundary value problem （BVP） of the antiplane elasticity or the Laplace equation. The Schwar...
