Title: Strict power convexity of solutions to elliptic partial differential equations
Time & Venue: 2026年5月21日（星期四）10：00-11：00 & 思源楼 S813
Abstract: The convexity of solutions to elliptic partial differential equations is an important issue. In this talk, we establish some strict power convexity results for fully nonlinear PDEs using the Constant Rank Theorem method. This is joint work with Haohao Jia, Jiawei Xiong, and Yan Ma.

Title: Flow Decomposition method and Liouville theorems
Time & Venue: 2026年5月21日（星期四）11：00-12：00 & 思源楼 S813
Abstract: We investigate quasilinear differential inequalities on weighted graphs. Using a flow decomposition method, we establish a sharp integral volume condition that leads to Liouville-type theorems.
