Abstract

For a given graph FF, the FF-saturation number of a graph GG, denoted by sat(G,F) {sat}(G, F), is the minimum number of edges in an edge-maximal FF-free subgraph of GG. In 2017, Kor\'andi and Sudakov determined sat(G(n,p),Kr) {sat}({G}(n, p), K_r) asymptotically, where G(n,p){G}(n, p) denotes the Erd\H{o}s-R\'enyi random graph and Kr K_r is the complete graph on rr vertices. In this paper, among other results, we present an asymptotic upper bound on sat(G(n,p),F){sat}({G}(n, p), F) for any bipartite graph FF and also an asymptotic lower bound on sat(G(n,p),F){sat}({G}(n, p), F) for any complete bipartite graph FF.
