Question:

is there a special name for matrices whose rows and columns sum to zero?

I actually need information about those matrices and thus a keyword for online search.

Edit: as there apparently is no name for those kind of matrices, I would like to suggest ,"Vibration Matrices" for discussion, because vibrating membranes exhibit an analogous property with respect to the unexcited state as the zero-level.

Further edit:
Laplacian Matrices are integer valued examples of diagonally dominant matrices with vanishing row- and column sums.

    $\begingroup$ That was not on intent, I had forgotten about my earlier question, but still I would appreciate a keyword for those kind of matrices or, if there isn't one in use, suggestions for such a name. $\endgroup$

    $\begingroup$ Note that if $S$ is doubly-stochastic, then $S-I$ is your matrix. Maybe useful? $\endgroup$

    $\begingroup$ @kjetilbhalvorsen true, but not all of 'my' matrices are of that structure because $|a_{ij}|\le 1$ for doubly stochastic matrices, whereas no such restriction exists for 'my' matrices. Of course every zero linesum matrix can be scaled to satisfy $\max(|a_{ij})|\in \lbrace 0,1\rbrace$ $\endgroup$
