Abstract

We consider tautologies formed from a pseudo-random number generator, defined in Krajíček [11] and in Alekhnovich et al. [2]. We explain a strategy of proving their hardness for Extended Frege systems via a conjecture about bounded arithmetic formulated in Krajíček [11]. Further we give a purely finitary statement, in the form of a hardness condition imposed on a function, equivalent to the conjecture.
