TY - JOUR T1 - On Path Laplacian Eigenvalues and Path Laplacian Energy of Graphs AU - Patekar, Shridhar Chandrakant AU - Shikare, Maruti Mukinda PY - 2018 DA - January JF - Journal of New Theory JO - JNT PB - Naim ÇAĞMAN WT - DergiPark SN - 2149-1402 SP - 93 EP - 101 IS - 20 LA - en AB - We introduce the concept of Path Laplacian Matrix for a graph and explore the eigenvalues of this matrix. The eigenvalues of this matrix are called the path Laplacian eigenvalues of the graph. We investigate path Laplacian eigenvalues of some classes of graph. Several results concerning path Laplacian eigenvalues of graphs have been obtained. KW - Path KW - Real symmetric matrix KW - Laplacian matrix CR - [1] Lowel W. Beineke, Robin J.
