Linear and Sublinear Time Algorithms for Basis of Abelian Groups
It is well known that every finite abelian group G can be represented as a direct product of cyclic groups: G ∼= G1 × G2 × · · · × Gt, where each Gi is a cyclic group of ...

Efficient Isomorphism Testing for a Class of Group Extensions
Abstract. The group isomorphism problem asks whether two given groups are isomorphic or not. Whereas the case where both groups are abelian is well understood and can be solved eff...

An Efficient Quantum Algorithm for Some Instances of the Group Isomorphism Problem
In this paper we consider the problem of testing whether two finite groups are isomorphic. Whereas the case where both groups are abelian is well understood and can be solved effi...

Fast algorithms for differential equations in positive characteristic
We address complexity issues for linear differential equations in characteristic p > 0: resolution and computation of the p-curvature. For these tasks, our main focus is on al...

Linear Time Membership for a Class of XML Types with Interleaving and Counting
Regular Expressions (REs) form the basis of most XML type languages, such as DTDs, XML Schema types, and XDuce types (Thompson et al. 2004; Hosoya and Pierce 2003). In this contex...
