Two-weight, two-parameter fractional integration with one side condition
Lijuan Wang, Zhiming Wang, Zipeng Wang
We study a family of strong fractional integral operators whose kernels have singularity on every coordinate subspace. We prove a two-weight --norm inequality by allowing…

The Contour integral method for Feynman-Kac equation with two internal states
Fugui Ma, Lijing Zhao, Yejuan Wang +1
We develop the contour integral method for numerically solving the Feynman-Kac equation with two internal states [P. B. Xu and W. H. Deng, Math. Model. Nat. Phenom., 13 (2018), 10]…

Ergodic maximization problem for expanding maps with differentiable observables
X. Zhang
We show that for an expanding map, the maximizing measures of a generic (open and dense) () differentiable functions are supported on a single periodic orbit.…
