Symmetry Coincides with Nondeterminism for Time-Bounded Auxiliary Pushdown Automata
—We show that every language accepted by a nondeterministic auxiliary pushdown automaton in polynomial time (that is, every language in SAC1 = Log(CFL)) can be accepted by a symm...

Fast separable factorization and applications
Abstract. In this paper we show that the separable decomposition of a univariate polynomial can be computed in softly optimal time, in terms of the number of arithmetic operations ...

On the Relation between Polynomial Identity Testing and Finding Variable Disjoint Factors
We say that a polynomial f(x1, . . . , xn) is indecomposable if it cannot be written as a product of two polynomials that are defined over disjoint sets of variables. The polynom...

Probabilistic Polynomial-Time Semantics for a Protocol Security Logic
Abstract. We describe a cryptographically sound formal logic for proving protocol security properties without explicitly reasoning about probability, asymptotic complexity, or the ...

Learning a Subclass of Regular Patterns in Polynomial Time
An algorithm for learning a subclass of erasing regular pattern languages is presented. On extended regular pattern languages generated by patterns π of the form x0α1x1 . . . α...
