Stability for Effective Algebras
We give a general method for showing that all numberings of certain effective algebras are recursively equivalent. The method is based on computable approximation-limit pairs. The...

Construction of Rational Points on Elliptic Curves over Finite Fields
Abstract. We give a deterministic polynomial-time algorithm that computes a nontrivial rational point on an elliptic curve over a finite field, given a Weierstrass equation for the...

Exact finite approximations of average-cost countable Markov decision processes
For a countable-state Markov decision process we introduce an embedding which produces a finite-state Markov decision process. The finite-state embedded process has the same optim...

Conjugacy classes in finite permutation groups via homomorphic images
The lifting of results from factor groups to the full group is a standard technique for solvable groups. This paper shows how to utilize this approach in the case of non-solvable n...
