Operator Theory on the Pentablock

Abhay Jindal, Poornendu Kumar

The pentablock, denoted as $\cP,$ is defined as follows: $$\cP= \left\{ (a_{21}, {\rm tr}(A), {\rm det}(A)) : A = [a_{ij}]_{2 \times 2} \text{ with } \|A\|<1 \right\}.$$ It origina…

Complete Nevanlinna-Pick Kernels and the Curvature Invariant

Tirthankar Bhattacharyya, Abhay Jindal

We consider a unitarily invariant complete Nevanlinna-Pick kernel denoted by $s$ and a commuting $d$ -tuple of bounded operators $T = (T_{1}, \dots, T_{d})$ satisfying a natural con…
