One-sided Versus Two-sided Error in Probabilistic Computation
We demonstrate how to use Lautemann's proof that BPP is in p 2 to exhibit that BPP is in RPPromiseRP. Immediate consequences show that if PromiseRP is easy or if there exist q...

Algebrization: A New Barrier in Complexity Theory
Any proof of P = NP will have to overcome two barriers: relativization and natural proofs. Yet over the last decade, we have seen circuit lower bounds (for example, that PP does n...

Common knowledge in update logics
Current dynamic epistemic logics often become cumbersome and opaque when common knowledge is added for groups of agents. Still, postconditions regarding common knowledge express t...

Random Access to Advice Strings and Collapsing Results
We propose a model of computation where a Turing machine is given random access to an advice string. With random access, an advice string of exponential length becomes meaningful ...

Separating Complexity Classes Using Structural Properties
We study the robustness of complete sets for various complexity classes. A complete set A is robust if for any f(n)-dense set S ∈ P, A−S is still complete, where f(n) ranges f...
