摘要：

We consider integrals of type integral(on)u(11)(a1) ... u(1n)(an)u(21)(b1) ... u(2n)(bn)du, with respect to the Haar measure on the orthogonal group. We establish several remarkable invariance properties satisfied by such integrals, by using combinatorial methods. We present as well a general formula for such integrals, as a sum of products of factorials. (C) 2010 Elsevier Inc. All rights reserved.
