WebIn this paper, we investigate some properties of this graph invariant in terms of orbit structure of a graph and then we explore new bounds forsdd-index. In continuing, the inverse symmetric division deg index is defined and new results concerning these two graph indices are stablished. Finally, some bounds for both indices are presented. 展开 WebGRAPH OPERATIONS ON THE SYMMETRIC DIVISION DEG INDEX OF GRAPHS. Authors: C. K. Gupta , V. Lokesha, Shwetha B. S3 and Ranjini P. S4. file: …
