Quantum unitary group $U_{q, Θ} (3)$ for complex deformation parameters

Manabendra Giri, Debabrata Jana

In this article, we consider a particular Hayashi $R$ -matrix that satisfies the Yang-Baxter equation $R_{12} R_{13} R_{23} = R_{23} R_{13} R_{12}$ . Using the FRT-bialgebra technique and…

A few remarks on intermediate subalgebras of an inclusion of C*-algebras

Keshab Chandra Bakshi, Satyajit Guin, Debabrata Jana

We show that the angle between intermediate $C^{*}$ -subalgebras of an inclusion of simple $C^{*}$ -algebras with finite Watatani index is stable. The notion of angle is instrumental in…
