Comparison between the first Steklov eigenvalue and algebraic connectivity on trees
Huiqiu Lin, Da Zhao
Trees can be regarded as discrete analogue of Hadamard manifolds, namely simply-connected Riemannian manifolds of non-positive sectional curvature. In this paper, we compare the fi…

Maximize the Steklov eigenvalue of trees
Huiqiu Lin, Da Zhao
We study the maximal Steklov eigenvalues of trees with given number of boundary vertices and total number of vertices. Trees can be regarded as discrete analogue of Hadamard manifo…
