Native spaces and generalization of Wu functions
Yixuan Huang, Zongmin Wu, Shengxin Zhu
We prove that the native space of a Wu function is a dense subspace of a Sobolev space. An explicit characterization of the native spaces of Wu functions is given. Three definition…

Suboptimal subspace construction for log-determinant approximation
Zongyuan Han, Wenhao Li, Yixuan Huang +1
Variance reduction is a crucial idea for Monte Carlo simulation and the stochastic Lanczos quadrature method is a dedicated method to approximate the trace of a matrix function. In…
