Abstract:
An improvement of Riordan’s result on the threshold probability of the occurrence of a spanning subgraph in a random graph is obtained for some classes of subgraphs, which, in particular, implies an improved bound for the maximum power of a Hamiltonian cycle in a random graph. Moreover, the exact asymptotics of the threshold probability for the occurrence of spanning subgraphs from a wide class of $k$-degenerate graphs is found.
