Relative entropy and the multivariable multidimensional moment problem

Entropy-like functionals on operator algebras have been studied since the pioneering work of von Neumann, Umegaki, Lindblad, and Lieb. The best known are the von Neumann entropy |(rho):=-trace(rhologrho) and a generalization of the Kullback- Leibler distance S(rhoparsigma):=trace(rhologrho-rhologsig...
