This new characteristic is defined in terms of a given degree sequence as a graph invariant and gives a lot of information on the realizability, number of realizations, connectedness, cyclicness, number of components, chords, loops, pendant edges, faces, bridges etc. of the family of realizations.In this paper, the effect of the deletion of vertices and edges from a graph on omega invariant is studied.eninfo:eu-repo/semantics/openAccessRealizabilityOmega of a graphDegree sequenceConnectednessCyclic graphAcyclic graphScience & technologyPhysical sciencesMathematics, appliedMathematicsArticle00060307230001068569614310.2298/AADM190219046D
