### Degree sum adjacency polynomial of standard graphs and graph operations

#### Abstract

*D*

*S*

_{A}(

*G*) of a simple undirected graph

*G*. We state a relation between the structure of a graph with the coefficients of its

*D*

*S*

_{A}polynomial. We obtain a generating function to find the number of walks of length

*k*in a graph. Then, we obtain the degree sum adjacency polynomial for some standard graphs, derived graphs and for graph operations.
