CHROMATIC NUMBER OF 2-STRONG PRODUCT GRAPH.

Cartesian product, tensor product, and strong product are well-known product graphs, which have been studied in detail. Some of these products are generalized by defining 2-Cartesian product, 2-tensor product, and distance product. Additionally, certain basic graph parameters of these products have been studied. Recently, a new graph product, 2-strong product graph has been defined, and the connectedness of this graph has been discussed. In this paper, we studied chromatic number and clique number of 2-strong product graph. [ABSTRACT FROM AUTHOR]
