On Quantum Algorithms for Noncommutative Hidden Subgroups
Quantum algorithms for factoring and finding discrete logarithms have previously been generalized to finding hidden subgroups of finite Abelian groups. This paper explores the ...

A descending chain condition for groups definable in o-minimal structures
We prove that if G is a group definable in a saturated o-minimal structure, then G has no infinite descending chain of type-definable subgroups of bounded index. Equivalently, G h...
