On the equivariant triangulation of some small covers

Raju Kumar Gupta, Soumen Sarkar

In this paper, we study certain properties of $Z_{2}^{n}$ -equivariant triangulations of small covers. We show that any $Z_{2}^{n}$ -equivariant triangulation of a small co…

On the Vietoris-Rips Complexes of Integer Lattices

Raju Kumar Gupta, Sourav Sarkar, Samir Shukla

For a metric space $X$ and $r \geq 0$ , the Vietoris-Rips complex $V R (X; r)$ is a simplicial complex whose simplices are finite subsets of $X$ with diameter at most $r$ . Vi…

Simplicial degree $d$ self-maps on $n$ -spheres

Biplab Basak, Raju Kumar Gupta, Ayushi Trivedi

The degree of a map between orientable manifolds is a fundamental concept in topology, providing deep insights into the structure of manifolds and the behavior of maps between them…

A characterization of normal $3$ -pseudomanifolds with $g_{2} \leq 4$

Biplab Basak, Raju Kumar Gupta

We characterize normal $3$ -pseudomanifolds with $g_{2} \leq 4$ . We know that if a $3$ -pseudomanifold with $g_{2} \leq 4$ does not have any singular vertices then it is a $3$ -sphere. We fir…
