Abstract:An integer partition {lambda1,lambda2,...,lambda v } is said to be graphical if there exists a graph with degree sequence langlambda i rang. We give some results corcerning the problem of deciding whether or not almost all partitions of even integer are non-graphical. We also give asymptotic estimates for the number of partitions with given rank.
