On arc-density of pushably -critical oriented graphs
Tapas Das, Pavan P D, Sagnik Sen +1
An oriented graph is pushably -critical if it is not pushably -colorable, but every proper subgraph of is. The main result of this a…

Monitoring arc-geodetic sets of oriented graphs
Tapas Das, Florent Foucaud, Clara Marcille +2
Monitoring edge-geodetic sets in a graph are subsets of vertices such that every edge of the graph must lie on all the shortest paths between two vertices of the monitoring set. Th…

On fundamental results for pushable homomorphisms of oriented graphs
Tapas Das, Pavan P D, Sagnik Sen +1
This article deals with homomorphisms of oriented graphs with respect to push equivalence. Here homomorphisms refer to arc preserving vertex mappings, and push equivalence refers t…
