Non-trivial intersecting families for finite affine spaces
Chao Gong, Benjian Lv, Kaishun Wang
Guo and Xu determined the maximum size of intersecting families over finite affine spaces and showed that any family reaches maximum size must be trivial. In this paper, we charact…

Properties for CD Inequalities with Unbounded Laplacians
Cao Gong, Yong Lin
The CD equalities were introduced to imply the gradient estimate of laplace operator on graphs. This article is based on the unbounded Laplacians, and finally concludes some equiva…
