The structure of twisted power partial isometries

Athul Augustine, P. Shankar

Let $n > 1$ and let ${U_{ij}}_{1 \leq i < j \leq n}$ be $(2 n)$ commuting unitaries on a Hilbert space $H$ . Suppose $U_{j i} := U_{ij}^{*}$ , $1 \leq i < j \leq n$ . An n-tuple of…

On products of symmetries in von Neumann algebras

B V Rajarama Bhat, Soumyashant Nayak, P Shankar

Let $R$ be a type $I I_{1}$ von Neumann algebra. We show that every unitary in $R$ may be decomposed as the product of six symmetries (that is, self-adjoint unitar…
