Sažetak

Suppose ${\mu }_1$, ${\mu }_2$, ... , ${\mu }_n$ are Laplacian eigenvalues
of a graph $G$. The Laplacian energy of $G$ is defined as $LE(G)=\sum _{i=1}^n|{\mu }_i-2m/n|$. In this paper, some new bounds for
the Laplacian eigenvalues and Laplacian energy of some special
types of the subgraphs of $K_n$ are presented.
