Abstract
In this note we examine a possible extension of the matrix integral
representation of knot invariants beyond the class of torus knots. In
particular, we study a representation of the SU(2) quantum Racah coefficients
by double matrix integrals. We find that the Racah coefficients are mapped to
expansion coefficients in some basis of double integrals. The transformed
coefficients have a number of interesting algebraic properties.
