Isotropy group of Lotka-Volterra derivations

Himanshu Rewri, Surjeet Kour

In this paper, we study the isotropy group of Lotka-Volterra derivations of $K [x_{1}, \dots, x_{n}]$ , i.e., a derivation $d$ of the form $d (x_{i}) = x_{i} (x_{i - 1} - C_{i} x_{i + 1})$ . If $…

Hilbert spaces over $C^{*}$ -tensor categories, Fredholm modules and cyclic cohomology

Abhishek Banerjee, Subhajit Das, Surjeet Kour

We construct Fredholm modules over an algebra taking values in generalized Hilbert spaces over a rigid $C^{*}$ -tensor category. Using methods of Connes, we obtain Chern characters ta…

On $n^{t h}$ class preserving automorphisms of $n$ -isoclinism family

Surjeet Kour

Let $G$ be a finite group and $M, N$ be two normal subgroups of $G$ . Let $A u t_{N}^{M} (G)$ denote the group of all automorphisms of $G$ which fix $N$ element wise and act trivially on $G…
