Finite Free Point Processes

Adam W. Marcus

We use techniques from finite free probability to analyze matrix processes related to eigenvalues, singular values, and generalized singular values of random matrices. The models w…

Polynomial convolutions and (finite) free probability

Adam W. Marcus

We introduce a finite version of free probability and show the link between recent results using polynomial convolutions and the traditional theory of free probability. One tool fo…

A Determinantal Identity for the Permanent of a Rank 2 Matrix

Adam W. Marcus

We prove an identity relating the permanent of a rank matrix and the determinants of its Hadamard powers. When viewed in the right way, the resulting formula looks strikingly s…

Existence and polynomial time construction of biregular, bipartite Ramanujan graphs of all degrees

Aurelien Gribinski, Adam W. Marcus

We prove that there exist bipartite, biregular Ramanujan graphs of every degree and every number of vertices provided that the cardinalities of the two sets of the bipartition divi…

A class of multivariate polynomial convolutions (and applications)

Adam W. Marcus

We prove two "master" convolution theorems for multivariate determinantal polynomials. The methods used include basic properties of what we call a "minor-orthogonal" ensemble as we…

A rectangular additive convolution for polynomials

Aurelien Gribinski, Adam W. Marcus

We define the rectangular additive convolution of polynomials with nonnegative real roots as a generalization of the asymmetric additive convolution introduced by Marcus, Spielman…
