A Separation of NP and coNP in Multiparty Communication Complexity
: We prove that coNP MA in the number-on-forehead model of multiparty communication complexity for up to k = (1 - )logn players, where > 0 is any constant. Specifically, we con...

Tractable Reasoning in a Fragment of Separation Logic
Abstract. In 2004, Berdine, Calcagno and O’Hearn introduced a fragment of separation logic that allows for reasoning about programs with pointers and linked lists. They showed th...

Satisfiability Allows No Nontrivial Sparsification Unless The Polynomial-Time Hierarchy Collapses
Consider the following two-player communication process to decide a language L: The first player holds the entire input x but is polynomially bounded; the second player is computa...
