The Scale of ()-closed Groups Acting On Trees
Marcus Chijoff, Michal Ferov, Stephan Tornier
Reid--Smith parametrised ()-closed groups acting on trees using graph-based combinatorial structures known as local action diagrams. Properties of the acting (topological) group…
-Hereditarily conjugacy separable groups and wreath products
Alex Bishop, Alexander Bishop, Michal Ferov +1
We provide a necessary and sufficient condition for the restricted wreath product to be -hereditarily conjugacy separable where is an extension-…
On the non-discreteness of automorphism groups of Cayley graphs of Coxeter groups
Federico Berlai, Michal Ferov
In this work we characterise Cayley graphs of Coxeter groups with respect to the standard generating set that admit uncountable vertex stabilisers. As a corollary, we fully identif…
Survey on effective separability
Jonas Deré, Michal Ferov, Mark Pengitore
Separability for groups refers to the question which subsets of a group can be detected in its finite quotients. Classically, separability is studied in terms of which classes have…
Bounding conjugacy depth functions for wreath products of finitely generated abelian groups
Michal Ferov, Mark Pengitore
In this article, we study the asymptotic behaviour of conjugacy separability for wreath products of abelian groups. We fully characterise the asymptotic class in the case of lampli…
Conjugacy depth function for generalised lamplighter groups
Michal Ferov, Mark Pengitore
In this article, we completely characterize the asymptotic behavior of conjugacy separability for the lamplighter groups. More generally, we give exponential upper and lower bounds…
Density of Metric Small Cancellation in Finitely Presented Groups
Alex Bishop, Michal Ferov
Small cancellation groups form an interesting class with many desirable properties. It is a well-known fact that small cancellation groups are generic; however, all previously know…
Quantifying conjugacy separability in wreath products of groups
Michal Ferov, Mark Pengitore
We study generalisations of conjugacy separability in restricted wreath products of groups. We provide an effective upper bound for -conjugacy separability of a wreath…
Separating cyclic subgroups in graph products of groups
Federico Berlai, Michal Ferov
We prove that the property of being cyclic subgroup separable, that is having all cyclic subgroups closed in the profinite topology, is preserved under forming graph products. Furt…
Applications of L systems to group theory
Laura Ciobanu, Murray Elder, Michal Ferov
L systems generalise context-free grammars by incorporating parallel rewriting, and generate languages such as EDT0L and ET0L that are strictly contained in the class of indexed la…
Enhancing LambdaMART Using Oblivious Trees
Michal Ferov, Marek Modrý
Learning to rank is a machine learning technique broadly used in many areas such as document retrieval, collaborative filtering or question answering. We present experimental resul…
Residual properties of graph products of groups
Federico Berlai, Michal Ferov
We prove that the class of residually C groups is closed under taking graph products, provided that C is closed under taking subgroups, finite direct products and that free-by-C gr…
Separability properties of automorphisms of graph products of groups
Michal Ferov
We study properties of automorphisms of graph products of groups. We show that graph product has non-trivial pointwise inner automorphisms if and only if some vertex…
On conjugacy separability of graph products of groups
Michal Ferov
We show that the class of -hereditarily conjugacy separable groups is closed under taking arbitrary graph products whenever the class is an extension clo…
