Completely bounded kernels
Tirthankar Bhattacharyya, Michael A. Dritschel, Christopher S. Todd
We introduce completely bounded kernels taking values in L(A,B) where A and B are C*-algebras. We show that if B is injective such kernels have a Kolmogorov decomposition precisely…
On c.n.c. commuting contractive tuples
T. Bhattacharyya, J. Eschmeier, J. Sarkar
The characteristic function has been an important tool for studying completely non unitary contractions on Hilbert spaces. In this note, we consider completely non-coisometric cont…
Standard noncommuting and commuting dilations of commuting tuples
B. V. Rajarama Bhat, Tirthankar Bhattacharyya, Santanu Dey
We introduce a notion called `maximal commuting piece' for tuples of Hilbert space operators. Given a commuting tuple of operators forming a row contraction there are two commonly…
