Abstract: We determine the closure of a cyclic subgroup H of a free group for the pro-V topology when V is an extension-closed pseudovariety of finite groups. We show that H is always closed for the pro-nilpotent topology and compute its closure for the pro-G(p) and pro- V-p topologies, where G(p) is the pseudovariety of finite p-groups and V-p superset of G(p) denote the pseudovarieties involved in the join decomposition of the pseudovariety of finite supersolvable groups. More generally, given any nonempty set P of primes, we consider the stated problem for the pseudovariety G(P) of all finite groups having order a product of primes in P.2025-01-01T00:00:00ZGeodesic languages for rational subsets and conjugates in virtually free groupshttps://hdl.handle.net/10216/1746432026-06-29T06:59:05Z2026-01-01T00:00:00ZTitle: Geodesic languages for rational subsets and conjugates in virtually free groups
Abstract: We prove that a subset of a virtually free group is rational if and only if the language of geodesic words representing its elements (in any generating set) is rational and that the language of geodesics representing conjugates of elements in a rational subset of a virtually free group is context-free. As a corollary, the doubly generalized conjugacy problem is decidable for rational subsets of finitely generated virtually free groups: there is an algorithm taking as input two rational subsets K1 and K2 of a virtually free group that decides whether there is one element of K1 conjugate to an element of K2. For free groups, we prove that the same problem is decidable with rational constraints on the set of conjugators. (c) 2026 The Author(s). Published by Elsevier Inc.

Abstract: We introduce the pseudovariety of finite groups U =boolean OR(p is an element of & Popf;)Ab(p) & lowast;Ab(p - 1), where & Popf; is the set of all primes. We show that U consists of all finite supersolvable groups with elementary abelian derived subgroup and abelian Sylow subgroups, and so U has decidable membership problem. We prove that it is decidable whether or not a finitely generated subgroup of a free group is closed or dense for the pro-U topology. We consider also the pseudovariety of finite groups Ab(p) & lowast;Ab(d) (where p is a prime and d divides p - 1). We study the pro-(Ab(p) & lowast;Ab(d)) topology on a free group and construct the unique generator of minimum size of the pseudovariety Ab(p) & lowast;Ab(d). Finally, we prove that the variety of groups generated by U is the variety of all metabelian groups, obtaining also results on the varieties generated by a Baumslag-Solitar group of the form BS(1,q) for q prime.2026-01-01T00:00:00ZSolar Photoelectrochemical Energy Storage: Materials Deviceshttps://hdl.handle.net/10216/947362026-06-28T06:40:51Z2016-06-27T00:00:00ZTitle: Solar Photoelectrochemical Energy Storage: Materials Devices2016-06-27T00:00:00Z
