Zeros of 2 × 2 Matrix Polynomials

, 2009
Consider the nth degree polynomial equation, X n + A n−1 X n−1 + … +A 1 X + A 0 = 0 over the ring of 2 × 2 complex matrices. If this equation has more than solutions, then it has infinitely many solutions.

The Ginibre Ensemble of Real Random Matrices and its Scaling Limits

, 2008
We give a closed form for the correlation functions of ensembles of a class of asymmetric real matrices in terms of the Pfaffian of an antisymmetric matrix formed from a 2 × 2 matrix kernel associated to the ensemble.
