Spectra of new graph operations based on central graph
T K Jahfar, A V Chithra
In this paper, we introduce central vertex corona, central edge corona, and central edge neighborhood corona of graphs using central graph. Also, we determine their adjacency spect…

Construction of equienergetic and Randic' equienergetic graphs
T K Jahfar, A V Chithra
In this paper, we give several constructions for the pairs of graphs to be equienergetic and Randic' equienergetic graphs. Also, some new families of integral and Randic' integral…

Orderenergetic, hypoenergetic and equienergetic graphs resulting from some graph operations
Jahfar TK, Chithra AV
A graph G is said to be orderenergetic, if its energy equal to its order and it is said to be hypoenergetic if its energy less than its order. Two non-isomorphic graphs of same ord…
