Packing Hamilton cycles in random graphs

How many edge disjoint Hamilton cycles can one pack in a graph G? Since every such cycle consumes exactly two edges incident to every vertex of G, the obvious upper bound for this quantity is one half of the minimum degree of G (rounded down, to be more accurate). In our recent work with Alan Frieze we show that for the random graph G(n,p), as long as the edge probability p(n) satisfies: p(n)=o(log n) this trivial upper bound is almost surely tight.

In my talk I will discuss this result, its predecessors and (conjectured) successors, and will also indicate some ideas used in its proof.
