We construct biorthogonal polynomials for a measure over the complex plane which consists in the exponential of a potential −V (z, z *) and in a set of external sources at the numerator and at the denominator. We use the pseudonorm of these polynomials to calculate the resolvent integral for correlation functions of traces of powers of complex matrices(More)
For a restricted class of potentials (harmonic+Gaussian potentials), we express the resolvent integral for the correlation functions of simple traces of powers of complex matrices of size N , in term of a determinant; this determinant is function of four kernels constructed from the orthogonal polynomials corresponding to the potential and from their Cauchy(More)
We write the loop equations for the β two-matrix model, and we propose a topological recursion algorithm to solve them, order by order in a small parameter. We find that to leading order, the spectral curve is a " quantum " spectral curve, i.e. it is given by a differential operator (instead of an algebraic equation for the hermitian case). Here, we study(More)
