Beauville Structures for Quotients of Generalised GGS-groups [PDF]
Advances in Group Theory and ApplicationsA finite group with a Beauville structure gives rise to a certain compact complex surface called a Beauville surface. Gül and Uria-Albizuri showed that quotients of the periodic Grigorchuk-Gupta-Sidki (GGS-)groups that act on the p-adic tree, for p an ...

Tracking Seed Fates of Tropical Tree Species: Evidence for Seed Caching in a Tropical Forest in North-East India. [PDF]
PLoS ONE, 2015 Rodents affect the post-dispersal fate of seeds by acting either as on-site seed predators or as secondary dispersers when they scatter-hoard seeds. The tropical forests of north-east India harbour a high diversity of little-studied terrestrial murid and

On invertor elements and finitely generated subgroups of groups acting on trees with inversions
International Journal of Mathematics and Mathematical Sciences, 2000 An element of a group acting on a graph is called invertor if it transfers an edge of the graph to its inverse. In this paper, we show that if G is a group acting on a tree X with inversions such that G does not fix any element of X, then an element g of

DIVERSIFICATION INTO THE GENUS Badnavirus: PHYLOGENY AND POPULATION GENETIC VARIABILITY
Ciência Agrícola, 2019 Badnaviruses (family Caulimoviridae) have semicircular dsDNA genomes encapsidated into bacilliform particles. The genus Badnavirus is the most important due to its high number of species reported infecting cultivated plants worldwide. This study aimed to

Locally compact groups acting on trees [PDF]
Pacific Journal of Mathematics, 1982 Following Serre's original description of groups having the fixed point property for actions on trees, Bass has introduced the notion of a group of type FA'. Groups of type FA' can not be nontrivial free products with amalgamation. We show that a locally compact (hausdorff) topological group with a compact set of connected components is of type FA ...

GROUPS ACTING ON TREES WITH PRESCRIBED LOCAL ACTION
Journal of the Australian Mathematical Society, 2022 AbstractWe extend the Burger–Mozes theory of closed, nondiscrete, locally quasiprimitive automorphism groups of locally finite, connected graphs to the semiprimitive case, and develop a generalization of Burger–Mozes universal groups acting on the regular tree $T_{d}$ of degree $d\in \mathbb {N}_{\ge 3}$ . Three applications are given.

International Journal of Mathematics and Mathematical Sciences, 2002 We extend the structure theorem for the subgroups of the class of HNN groups to a new class of groups called quasi-HNN groups. The main technique used is the subgroup theorem for groups acting on trees with inversions.

C*-simplicity of HNN extensions and groups acting on trees [PDF]
, 2020 We study non-ascending HNN extensions acting on their Bass– Serre tree and characterize C*-simplicity and the unique trace property by means of the kernel and quasi-kernels of the HNN extension in question.
