We determine the asymptotic distribution of the p-rank of the sandpile groups of random bipartite graphs. We see that this depends on the ratio between the number of vertices on each side, with a threshold when the ratio between the sides is equal to

We consider random directed graphs, and calculate the distribution of the cokernels of their laplacian, following the methods used by Wood. As a corollary, we show that the probability that a random digraph is coeulerian is asymptotically upper bound

We show that under reasonable conditions, a random n × ( 2 + ϵ ) n integer matrix is surjective on Z n with probability 1 − O ( e − c n ) . We also conjecture that this should hold for n × ( 1 + ϵ ) n , and provide a counterexample to show th
