Levin methods for highly oscillatory integrals with singularities
Yinkun Wang, Shuhuang Xiang
In this paper, new Levin methods are presented for calculating oscillatory integrals with algebraic and/or logarithmic singularities. To avoid singularity, the technique of singula…

Sparse Solutions of a Class of Constrained Optimization Problems
Lei Yang, Xiaojun Chen, Shuhuang Xiang
In this paper, we consider a well-known sparse optimization problem that aims to find a sparse solution of a possibly noisy underdetermined system of linear equations. Mathematical…

A Levin method for logarithmically singular oscillatory integrals
Yinkun Wang, Shuhuang Xiang
We propose a new stable Levin method to compute oscillatory integrals with logarithmic singularities and without stationary points. To avoid the singularity, we apply the technique…
