Kaplansky's second test problem in operator algebras

Chunlan Jiang, Minghui Ma, Rui Shi +1

Kaplansky's second test problem on similarity asks: if and are elements in a unital Banach algebra and is similar to in $\mathbb{M}_2(…

Intertwining Properties for Bimodule Quantum Markov Semigroups

Chunlan Jiang, Jincheng Wang, Jinsong Wu

In this paper, we study the Bakry-Émery estimates for GNS- and KMS-symmetric semigroups in terms of the Fourier multiplier of the gradient form and the iterated gradient form in t…

Bimodule KMS Symmetric Quantum Markov Semigroups and Gradient Flows

Chunlan Jiang, Jincheng Wan, Jinsong Wu

The bimodule KMS symmetry of a bimodule quantum Markov semigroup extends the classical KMS symmetry of a quantum Markov semigroup. Compared with (bimodule) GNS symmetry, the (bimod…

Density of irreducible operators in the trace-class norm

Junsheng Fang, Chunlan Jiang, Minghui Ma +3

In 1968, Paul Halmos initiated the research on density of the set of irreducible operators on a separable Hilbert space. Through the research, a long-standing unsolved problem inqu…

Completely Bounded Representations Into Von Neumann Algebras And Connes Embedding Problem

Junsheng Fang, Chunlan Jiang, Liguang Wang +1

In this paper, we prove that if is a unital separable -algebra, is a von Neumann algebra which has the Kirchberg's quotient weak expectation proper…
