Some inequalities for the Fan product of M-tensors [PDF]

Journal of Inequalities and Applications, 2018
In this paper, we investigate some inequalities for the Fan product of M-tensors. We propose exact characterizations of M-tensors and establish some inequalities on the minimum eigenvalue for the Fan product of two M-tensors.

Smooth fans that are endpoint rigid

Applied General Topology, 2023
Let X be a smooth fan and denote its set of endpoints by E(X). Let E be one of the following spaces: the natural numbers, the irrational numbers, or the product of the Cantor set with the natural numbers. We prove that there is a smooth fan X such that E(
