摘要
We formulate several open problems and conjectures involving acyclic doubly stochastic matrices with minimum permanent and the minimum second largest eigenvalue. New characterizations and illustrative examples of these permanental minimizing matrices are provided in this article. In addition, we show that the adjacency matrix of any tree, with more than 2 vertices, plus the identity matrix is not cohesive.
