Suppose that A is an nxn matrix, for which all non diagonal entries are non-negative and all diagonal entries are negative.
M=eA
What properties does M have? I know it has no negative entries, but what else can be said about it?
Now let's say N=eAeB. (B is from the same set as A). What can be said about N?
