Analysis of the Plancherel weight and factoriality of the group von Neumann algebras of non-unimodular almost unimodular groups

Yuki Miyamoto

Let $G$ be a locally compact group, $L (G)$ be its group von Neumann algebra equipped with the Plancherel weight $φ_{G}$ . In this paper, we consider the following two questions. (1) W…

Proof of the Paszkiewicz's conjecture about a product of positive contractions

Hiroshi Ando, Yuki Miyamoto, Narutaka Ozawa

The Paszkiewicz conjecture about a product of positive contractions asserts that given a decreasing sequence $T_{1} \geq T_{2} \geq \dots$ of positive contractions on a separable infinite-…
