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…

Lower bounds for regular genus and gem-complexity of PL 4-manifolds with boundary

Biplab Basak, Manisha Binjola

Let $M$ be a connected compact PL 4-manifold with boundary. In this article, we have given several lower bounds for regular genus and gem-complexity of the manifold $M$ . In particu…

Three-dimensional normal pseudomanifolds with relatively few edges

Biplab Basak, Ed Swartz

Let $Δ$ be a $d$ -dimensional normal pseudomanifold, $d \geq 3.$ A relative lower bound for the number of edges in $Δ$ is that $g_{2}$ of $Δ$ is at least $g_{2}$ of the link of any verte…
