Local homology properties of boundaries of groups. [PDF]
Michigan Mathematical Journal, 1996 Let \(\widetilde X\) be a Euclidean retract, ER (embeddable in some Euclidean space as a retract). A closed subset \(Z\) of \(\widetilde X\) is a \(Z\)-set if there is deformation \(h_t\): \(\widetilde X\to \widetilde X\) with \(h_0= \text{id}\) and \(h_t(\widetilde X) \cap Z= \emptyset\) for \(t>0\) (two equivalent definitions are given).

THE OBSERVED PROPERTIES OF DWARF GALAXIES IN AND AROUND THE LOCAL GROUP [PDF]
The Astronomical Journal, 2012 Positional, structural and dynamical parameters for all dwarf galaxies in and around the Local Group are presented, and various aspects of our observational understanding of this volume-limited sample are discussed. Over 100 nearby galaxies that have distance estimates placing them within 3Mpc of the Sun are identified.

Local interactions and global properties of wild, free-ranging stickleback shoals [PDF]
Royal Society Open Science, 2017 Collective motion describes the global properties of moving groups of animals and the self-organized, coordinated patterns of individual behaviour that produce them. We examined the group-level patterns and local interactions between individuals in wild,

Global and local properties of finite groups with only finitely many\n central units in their integral group ring [PDF]
Journal of group theroy, 2018 The aim of this article is to explore global and local properties of finite groups whose integral group rings have only trivial central units, so-called cut groups.

Imaging the dynamic influence of functional groups on metal-organic frameworks
Nature Communications, 2023 Metal-organic frameworks (MOFs) with different functional groups have wide applications, while the understanding of functionalization influences remains insufficient.

Finiteness Properties of Some Groups of Local Similarities [PDF]
Proceedings of the Edinburgh Mathematical Society, 2015 AbstractHughes has defined a class of groups that we call finite similarity structure (FSS) groups. Each FSS group acts on a compact ultrametric space by local similarities. The best-known example is Thompson’s group V. Guided by previous work on Thompson’s group, we show that many FSS groups are of type F∞.

Local topological properties of asymptotic cones of groups [PDF]
Algebraic & Geometric Topology, 2014 We define a local analogue to Gromov's loop division property which is use to give a sufficient condition for an asymptotic cone of a complete geodesic metric space to have uncountable fundamental group. As well, this property is used to understand the local topological structure of asymptotic cones of many groups currently in the literature.

Local to global property in free groups [PDF]
, 2019 The local to global property for an equation $ $ over a group G asks to show that $ $ is solvable in G if and only if it is solvable in every finite quotient of G. In this paper we focus that in order to prove this local to global property for free groups $G=F_k$, it is enough to prove for k less or equal the number of parameters in $ $.

On Local Embedding Properties of Injectors of Finite Soluble Groups [PDF]
Journal of the Australian Mathematical Society, 2004 AbstractIn the present paper we consider Fitting classes of finite soluble groups which locally satisfy additional conditions related to the behaviour of their injectors. More precisely, we study Fitting classes 1 ≠⊆such that an-injector of G is, respectively, a normal, (sub)modular, normally embedded, system permutable subgroup of G for all G ...
