Journal of Operator Theory, Vol. 69, No. 2 (Spring 2013), pp. 435-461 (27 pages) We exhibit unbounded operators on Banach spaces having the single-valued extension property, for which the local ...
We consider the skew Laplacian matrix of a digraph G → obtained by giving an arbitrary direction to the edges of a graph G having n vertices and m edges. We obtain an upper bound for the skew ...
