Invariant Integration over the Unitary Group
Integrals for the product of unitary-matrix elements over the U (n) group will be discussed. A group-theoretical formula is available to convert them into a multiple sum, but unfortunately the sums are often tedious to compute. In this paper, we develop an alternative method in which these sums are avoided, and group theory is rendered unnecessary. Only unitarity and the invariance of the Haar ...
متن کاملOn polynomial integrals over the orthogonal group
We consider integrals of type ∫ On u1 11 . . . u an 1nu b1 21 . . . u bn 2n 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. Introduction The computation of polynomial integral...
متن کاملIntegrals of monomials over the orthogonal group
A recursion formula is derived which allows one to evaluate invariant integrals over the orthogonal group O(N), where the integrand is an arbitrary finite monomial in the matrix elements of the group. The value of such an integral is expressible as a finite sum of partial fractions in N . The recursion formula largely extends presently available integration formulas for the orthogonal group. © ...
متن کاملIntegration over the Pauli Quantum Group
The notion of free quantum group appeared in Wang’s papers [17], [18]. The idea is that given a compact group G ⊂ Un, the matrix coordinates uij ∈ C(G) commute with each other, and satisfy certain relations R. One can define then the universal algebra A generated by abstract variables uij, subject to the relations R. In certain situations we get a Hopf algebra in the sense of Woronowicz [20], a...
متن کاملApproximating the Little Grothendieck Problem over the Orthogonal Group
The little Grothendieck problem (a special case of Boolean quadratic optimization) consists of maximizing ∑ ij Cijxixj over binary variables xi ∈ {±1}, where C is a positive semidefinite matrix. In this paper we focus on a natural generalization of this problem, the little Grothendieck problem over the orthogonal group. Given C ∈ Rdn×dn a positive semidefinite matrix, the objective is to maximi...
