A method of integration over matrix variables. III. (English) Zbl 0745.28006
Summary: For some applications an evaluation of the integral \(Z=\int\exp[-tr V(M)]dM\) over all \(n\times n\) (i) real symmetric, (ii) complex Hermitean, and (iii) quaternion self-dual matrices \(M\) is needed. Here \(V(x)\) is an even polynomial. The case (ii) is known for several years now. We present here a parallel study of the cases (i) and (iii).
