摘要： The quasicentral modulus is a number associated with an n-tuple of bounded Hilbert space operators and a rearrangement invariant norm. It underlies the multivariable generalizations of the classical theorems of Weyl-von Neumann-Kuroda and Kato-Rosenblum on perurbation theory. It also provides an operator theory approach to Lebesgue measure and to certain other self-similar measures on fractals, as well as to the Kolmogorov-Sinai dynamical entropy. I will explain a non-commutative analogy with condenser capacity in nonlinear potential theory.
