The bounded derived categories of an algebra with radical squared zero
Raymundo Bautista, Shiping Liu
Let $\La$ be an elementary locally bounded linear category over a field with radical squared zero. We shall show that the bounded derived category $D^b(\ModbLa)$ of finitely suppor…
Ricci curvature and eigenvalue estimates for the magnetic Laplacian on manifolds
Michela Egidi, Shiping Liu, Florentin Münch +1
In this paper, we present a Lichnerowicz type estimate and (higher order) Buser type estimates for the magnetic Laplacian on a closed Riemannian manifold with a magnetic potential.…
Bakry-Emery curvature and diameter bounds on graphs
Shiping Liu, Florentin Münch, Norbert Peyerimhoff
We prove diameter bounds for graphs having positive Ricci-curvature bound in Bakry-Emery sense. One result using only curvature and maximal vertex degree is sharp in case of hyperc…
Bakry-Émery curvature functions of graphs
David Cushing, Shiping Liu, Norbert Peyerimhoff
We study the Bakry-Émery curvature function of a vertex in a locally finite graph systematically. Here $\mathcal{K}_{G,x}(\math…
