Finitely presented kernels of right-angled Artin groups with abelian quotients
Mallika Roy
In this article, we characterise when the kernels of right-angled Artin groups with abelian quotients are finitely generated and finitely presented -- exhibiting an explicit finite…
The finitely generated intersection property in fundamental groups of graphs of groups
Jordi Delgado, Marco Linton, Jone Lopez de Gamiz Zearra +2
A group is said to satisfy the finitely generated intersection property (f.g.i.p.) if the intersection of any two finitely generated subgroups of is again finitely generate…
Pullbacks and intersections in categories of graphs of groups
Jordi Delgado, Marco Linton, Jone Lopez de Gamiz Zearra +2
We develop a categorical framework for studying graphs of groups and their morphisms, with emphasis on pullbacks. More precisely, building on classical work by Serre and Bass, we g…
Endo-Twisted Conjugacy and Outer Fixed Points in Solvable Baumslag--Solitar Groups
Mallika Roy
In this article, we solve the twisted conjugacy problem with respect to endomorphisms for solvable Baumslag--Solitar groups , i.e., we propose an algorithm which, given tw…
Twisted conjugacy in
Oorna Mitra, Mallika Roy, Enric Ventura
In this article, we solve the twisted conjugacy problem for solvable Baumslag--Solitar groups , i.e., we propose an algorithm which, given two elements a…
Bogomolov multipliers of word labelled oriented graph groups
Mallika Roy
A group, whose presentation is explicitly derived in a certain way from a word labelled oriented graph (in short, WLOG), is called a WLOG group. In this work, we study homological…
