Weak Centrality of unital C(X)-algebras
Bharat Talwar, Prahlad Vaidyanathan, Stefan Wagner
This paper establishes a fibrewise characterization of weak centrality for unital -algebras whose defining homomorphism maps onto the center: such an algebra is weakly…
Nonexistence of solutions of certain semilinear heat equations
Durvudkhan Suragan, Bharat Talwar
We consider a semilinear heat equation involving a forcing term which depends only on the space variable. To start with, the existence of a local mild solution is proved through an…
Local and Global Analysis of Semilinear Heat Equations with Hardy Potential on Stratified Lie Groups
Durvudkhan Suragan, Bharat Talwar
On stratified Lie groups we study a semilinear heat equation with the Hardy potential, a power non-linearity and a forcing term which depends only upon the spacial variable. The an…
Peripheral Poisson Boundary
B. V. Rajarama Bhat, Samir Kar, Bharat Talwar
It is shown that the operator space generated by peripheral eigenvectors of a unital completely positive map on a von Neumann algebra has a -algebra structure. This extends th…
