摘要
考虑强凸有界区域上的核函数的渐近展开式,我们用边界超曲面的Gauss曲率、Fubini-Pick不变量和仿射平均曲率来确定这个展开式中的第一个系数.
Considering the asymptotic expansion of the kernel function on a strongly convex bounded domain,we use the Gauss curvature,Fubini-Pick invariant and affine mean curvature of the boundary hypersurface to determine the first coefficient in the expansion.
