Deformations of Q-curvature II

Yueh-Ju Lin, Wei Yuan

This is the second article of a sequence of research on deformations of Q-curvature. In the previous one, we studied local stability and rigidity phenomena of Q-curvature. In this…

Pointed Drinfeld center functor

Liang Kong, Wei Yuan, Hao Zheng

In this work, using the functoriality of Drinfeld center of fusion categories, we generalize an earlier result on the functoriality of full center of simple separable algebras in a…

Ricci-flat graphs with girth four

Weihua He, Jun Luo, Chao Yang +1

Lin-Lu-Yau introduced an interesting notion of Ricci curvature for graphs and obtained a complete characterization for all Ricci-flat graphs with girth at least five [1]. In this p…

Brown-York mass and positive scalar curvature II - Besse's conjecture and related problems

Yi Fang, Wei Yuan

The Besse's conjecture was posted on the well-known book Einstein manifolds by Arthur L. Besse, which describes the critical point of Hilbert-Einstein functional with constraint of…

Brown-York mass and positive scalar curvature I - First eigenvalue problem and its applications

Wei Yuan

In this article, we investigate the connection between scalar curvature and first eigenfunctions via positive mass theorem for Brown-York mass. For compact manifolds with nice boun…

Wigner-Type Theorem on transition probability preserving maps in semifinite factors

Wenhua Qian, Liguang Wang, Wenming Wu +1

The Wigner's theorem, which is one of the cornerstones of the mathematical formulation of quantum mechanics, asserts that every symmetry of quantum system is unitary or anti-unitar…
