| heal.abstract | In this paper, we determine the minimal separators of P-4-sparse graphs and establish bounds on their number. Specifically, we show that a P-4-sparse graph G on n vertices and to edges has fewer than 2n/3 minimal separators of total description size at most 4m/3. The bound on the number of minimal separators is tight and is also tight for the class of cographs, a well known subclass of the P-4-sparse graphs. Our results enable us to present a linear-time and linear-space algorithm for computing the number of minimal separators of a given P-4-sparse graph; the algorithm can be modified to report the minimal separators of the input graph in linear time and space as well.
