On optimal heuristic randomized semidecision procedures, with applications to proof complexity and cryptography
The existence of a (p-)optimal propositional proof system is a major open question in (proof) complexity; many people conjecture that such systems do not exist. Kraj

On a syntactic approximation to logics that capture complexity classes
We formulate a formal syntax of approximate formulas for the logic with counting quantifiers, SOLP, studied by us in [1], where we showed the following facts: (i) In the presence ...
