	Article:	ON APPLICATIONS OF ANDRICA-BADEA AND NAGY INEQUALITIES IN SPECTRAL GRAPH THEORY. Authors: .


	Abstract: Applications of Andrica-Badea and Nagy inequalities for determining bounds of graph invariants of undirected, connected graphs are investigated. We consider bounds of the following invariants: the first Zagreb index, general Randic index, Laplacian linear spread and normalized Laplacian spread of graphs. Mathematics Subject Classification (2010): 60E15, 05C50. Keywords: Inequalities, rst Zagreb index, spread of graph.
