Abstract: We use the fermionic construction of two-matrix model partition functions to evaluate integrals over rational symmetric functions. This approach is complementary to the one used in our previous paper, where these integrals were evaluated by a direct method. Using Wick's theorem, we obtain the same determinantal expressions in terms of biorthogonal polynomials.
Keywords: random matrix, two-matrix model, multiple integral, factorization, dressing method, characteristic polynomial, free fermion.
