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…
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…
Peripherally automorphic unital completely positive maps
B. V. Rajarama Bhat, Samir Kar, Bharat Talwar
We identify and characterize unital completely positive (UCP) maps on finite dimensional -algebras for which the Choi-Effros product extended to the space generated by periphe…
Fujita exponent on stratified Lie groups
Durvudkhan Suragan, Bharat Talwar
We prove that is the Fujita exponent for a semilinear heat equation on an arbitrary stratified Lie group with homogeneous dimension . This covers the Euclidean c…
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…
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…
Center of Banach algebra valued Beurling algebras
Bharat Talwar, Ranjana Jain
We prove that for a Banach algebra having a bounded -approximate identity and for every group with weight which is either constant on conjugac…
On closed Lie ideals and center of generalized group algebras
Ved Prakash Gupta, Ranjana Jain, Bharat Talwar
For any locally compact group and any Banach algebra , a characterization of the closed Lie ideals of the generalized group algebra is obtained in terms of left a…
Lattice of intermediate subalgebras
Keshab Chandra Bakshi, Ved Prakash Gupta
Analogous to subfactor theory, employing Watatani's notions of index and -basic construction of certain inclusions of -algebras, (a) we develop a Fourier theory (consisti…
Closed ideals and Lie ideals of minimal tensor product of certain C*-algebras
Bharat Talwar, Ranjana Jain
For a locally compact Hausdorff space and a -algebra with only finitely many closed ideals, we discuss a characterization of closed ideals of in terms of c…
On closed Lie ideals of certain tensor products of C*-algebras II
Ved Prakash Gupta, Ranjana Jain, Bharat Talwar
We identify all closed Lie ideals of and , where is either the Haagerup tensor product, the Banach space projective tensor product…
