## Abstract A proper vertex coloring of a graph __G__β=β (__V,E__) is acyclic if __G__ contains no bicolored cycle. A graph __G__ is __L__βlist colorable if for a given list assignment __L__β=β{L(__v__): __v__ββ __V__}, there exists a proper coloring __c__ of __G__ such that __c__ (__v__)βββ__L__(_
The energy of a graph is the sum of the absolute values of the eigenvalues of its adjacency matrix. The edge grafting operation on a graph is certain kind of edge moving between two pendant paths starting from the same vertex. In this paper we show how the graph energy changes under the edge graftin
## Abstract If __G__ is any graph, a __Gβdecomposition__ of a __host__ graph __H__β=β(__V__, __E__) is a partition of the edge set of __H__ into subgraphs of __H__ which are isomorphic to __G__. The __chromatic index__ of a __G__βdecomposition is the minimum number of colors required to color the p
