报告摘要：
Sparse grid is a special discretization for high-dimensional problems. It is first introduced by S.A. Smolyak in 1960s for the integration and interpolation of tensor product functions. During the 1990s, C. Zenger et al. extended it to solve high-dimensional PDEs. The commonly used sparse grid bases are Fourier bases for periodic problems and linear finite element bases for non-periodic problems. In this talk, we introduce Chebyshev sparse grid method for solving non-periodic PDEs and apply it to solve the electronic Schrodinger equation.
