In science:

In the complex case, this integral can be evaluated using the Harish-Chandra (or Itzykson Zuber ) formula, while in the quarternionic case, the integral can be written as an infinite series in terms of Zonal polynomials and such series converges to a simple function in the rank 1 case.
