Mixed correlation functions of the two-matrix model
Mixed correlation functions of the two-matrix model
We compute the correlation functions mixing the powers of two non-commuting random matrices within the same trace. The angular part of the integration was partially known in the literature (Morozov A 1992 Mod. Phys. Lett. A 7 3503, Shatashvili S L 1993 Commun. Math. Phys. 154 421): we pursue the …
