Vibhor Bhatt, Satyajit Guin, Palash Sharma

We introduce a class of extensions of unital operator systems satisfying a certain Toeplitz type property and show that these extensions induce corresponding extensions of the $C^*…

Finite groups with mostly involuted cyclic subgroups

Vaibhav Chhajer, Palash Sharma

Let $G$ be a finite group. Let $C (G)$ be the set of cyclic subgroups of $G$ , $c (G) = ∣ C (G) ∣$ and $i (G) = {x \in G : x^{2} = e}$ . In this article, we classify finite groups…

Finite groups with nearly half as many cyclic subgroups as elements

Vaibhav Chhajer, Sumana Hatui, Palash Sharma

Suppose $C (G)$ denotes the set of all cyclic subgroups of a finite group $G$ , and $O_{2} (G)$ denotes the number of elements of order $2$ in $G$ . In [Marius T., Finite gro…
