SOFT MATRIX MODELS AND CHERN–SIMONS PARTITION FUNCTIONS
SOFT MATRIX MODELS AND CHERN–SIMONS PARTITION FUNCTIONS
We study the properties of matrix models with soft confining potentials. Their precise mathematical characterization is that their weight function is not determined by its moments. We mainly rely on simple considerations based on orthogonal polynomials and the moment problem. In addition, some of these models are equivalent, by a …
