On constructive characterizations of (k,l)-sparse graphs

László Szegő


In this paper we study constructive characterizations of graphs satisfying tree-connectivity requirements. The main result is the following: if k and l are positive integers and l \leq k/2, then a necessary and sufficient condition is proved for a node beeing the last node of a construction in a graph having at most k|X|-(k+l) induced edges in every subset X of nodes.
