Bounds for Functions of Dependent Risks
Abstract The problem of finding the best-possible lower bound on the distribution of a non-decreasing function of n dependent risks is solved when n = 2 and a lower bound on the co...

The Complexity of Games on Higher Order Pushdown Automata
Abstract. We prove an n-exptime lower bound for the problem of deciding the winner in a reachability game on Higher Order Pushdown Automata (HPDA) of level n. This bound matches th...
