Commutativity and Null Spaces of Unbounded Operators on Hilbert Space
Richard Kadison, Simon Levin, Zhe Liu
Based on the success of a well-known method for solving higher order linear differential equations, a study of two of the most important mathematical features of that method, viz.…
A note on commutators in algebras of unbounded operators
Richard V. Kadison, Zhe Liu, Andreas Thom
We show that the identity is the sum of two commutators in the algebra of all operators affiliated with a von Neumann algebra of type II, settling a question, in the negative,…
A Beurling Theorem for Generalized Hardy Spaces on a Multiply Connected Domain
Yanni Chen, Don Hadwin, Zhe Liu +1
The object of this paper is to prove a version of the Beurling-Helson-Lowdenslager invariant subspace theorem for operators on certain Banach spaces of functions on a multiply conn…
The Heisenberg Relation - Mathematical Formulations
Richard V. Kadison, Zhe Liu
We study some of the possibilities for formulating the Heisenberg relation of quantum mechanics in mathematical terms. In particular, we examine the framework discussed by Murray a…
