Fano Generalized Bott-Samelson Varieties
Narasimha Chary Bonala, Santosha Pattanayak, Yogendra Singh
The Bott-Samelson varieties provide natural desingularizations of Schubert varieties, and their generalizations, called generalized Bott-Samelson varieties, were constructed by Nic…
Characterisations of finite groups with exponent via their power graphs
Aditya Singh, Anmol chugh, Yogendra Singh +1
The power graph of a finite group is the graph with vertex set and edge set $E(P(G))=\{uv:\ u,v \in G,\ u \neq v,\ u \in \langle v \rangle \ \text{or}\ v \in \langle…
The Gromov width of generalized Bott-Samelson manifolds
Narasimha Chary Bonala, Yogendra Singh
We study the Gromov width of smooth generalized Bott-Samelson varieties, a class of projective varieties constructed by Perrin in \cite{Per07} as a generalization of classical Bott…
Spectral Properties of Power Graphs of Metacyclic Groups
Aditya Singh, Yogendra Singh, Anand Kumar Tiwari
For a group , the associated power graph is defined as the graph whose vertices are the elements of , with two distinct vertices being adjacent if either $u…
-Spectra of Joined Union Graphs with Applications to Power Graphs of Finite Groups
Aditya Singh, Yogendra Singh, Anand Kumar Tiwari
The \emph{generalized reciprocal distance matrix} of a graph , denoted by , is defined as $RD_α(\mathscr{G})=α\,RT_r(\mathscr{G})+(1-α)\,RD(\mathscr…
