Critical measures for vector energy: asymptotics of non-diagonal multiple orthogonal polynomials for a cubic weight

Andrei Martínez-Finkelshtein, Guilherme Silva

We consider the type I multiple orthogonal polynomials (MOPs) $(A_{n,m},B_{n,m})$ and type II MOPs $P_{n,m}$, satisfying non-hermitian orthogonality with respect to the weight $e^…
