In this paper we studied the asymptotic eigenvalue statistics of the 2 matrix model with the probability measure $$Z^{-1}_{n}{\rm exp}\left(-n\left({\rm tr}(V(M_1)+W(M_2)-\tau M_1M_2\right)\right) \, {\rm d}M_1{\rm d} M_2,$$in the case whereandVis a general even polynomial. We studied the correlation kernel for the eigenvalues of the matrixM1in the limit asn→ ∞. We extended the results of Duits and Kuijlaars in [14] to the case when the limiting eigenvalue density forM1is supported on multiple intervals. The results are achieved by constructing the parametrix to a Riemann-Hilbert problem obtained in [14] with theta functions and then showing that this parametrix is well-defined for allnby studying the theta divisor.
