Zero Products of Toeplitz operators on the Hardy and Bergman spaces over an annulus
Susmita Das, E. K. Narayanan
We study the zero product problem of Toeplitz operators on the Hardy space and Bergman space over an annulus. Assuming a condition on the Fourier expansion of the symbols, we show…
Mackey Imprimitivity and commuting tuples of homogeneous normal operators
Gadadhar Misra, E. K. Narayanan, Cherian Varughese
In this semi-expository article, we investigate the relationship between the imprimitivity introduced by Mackey several decades ago and commuting - tuples of homogeneous normal…
Unitary parts of Toeplitz operators with operator-valued symbols
E. K. Narayanan, Srijan Sarkar
Motivated by the canonical decomposition of contractions on Hilbert spaces, we investigate when contractive Toeplitz operators on vector-valued Hardy spaces on the unit disc admit…
Projective representations of Heisenberg groups over the rings of order p^2
Sumana Hatui, E. K. Narayanan, Pooja Singla
In this article we describe the 2-cocycles, Schur multiplier and representation group of discrete Heisenberg groups over the unital rings of order . We describe all projective…
Toeplitz operators on the weighted Bergman spaces of quotient domains
Gargi Ghosh, E. K. Narayanan
Let be a finite pseudoreflection group and be a bounded domain which is a -space. We establish identities involving Toeplitz operators on the weight…
Injectivity of spherical means on H-type groups
E. K. Narayanan, P. K. Sanjay, K. T. Yasser
We establish injectivity results for three different spherical means on an -type group, . First is the standard spherical means which is defined to be the average of a functi…
