On the fixed-parameter tractability of the equivalence test of monotone normal forms
We consider the problem Monet—given two monotone formulas ϕ in DNF and ψ in CNF, decide whether they are equivalent. While Monet is probably not coNPhard, it is a long standin...

Finding Small Triangulations of Polytope Boundaries Is Hard
We prove that it is NP-hard to decide whether a polyhedral 3-ball can be triangulated with k simplices. The construction also implies that it is difficult to find the minimal trian...

Breaking the rhythm on graphs
We study graph colorings avoiding periodic sequences with large number of blocks on paths. The main problem is to decide, for a given class of graphs F, if there are absolute const...
