چکیده
We describe homomorphisms $$\varphi :H\rightarrow G$$ for which G is acylindrically hyperbolic and H a topological group either completely metrizable or locally countably compact Hausdorff. It shown that, in certain sense, the image of $$ small almost continuous. also from Hawaiian earring to as above. prove more precise result {\text {Mod}}(\Sigma )$$ , where above $${\text mapping class connected surface $$\Sigma . In this case there exists an open normal subgroup $$V\leqslant H$$ such that (V)$$ finite. analogous statement {Out}}(G)$$ one-ended group. Some automatic continuity results relatively groups fundamental graphs are deduced. As by-product, we hyperbolic, but does not admit any universal acylindrical action on space.

Acylindrically hyperbolic groups
We say that a group G is acylindrically hyperbolic if it admits a non-elementary acylindrical action on a hyperbolic space. We prove that the class of acylindrically hyperbolic groups coincides with many other classes studied in the literature, e.g., the class Cgeom introduced by Hamenstädt, the class of groups admitting a non-elementary weakly properly discontinuous action on a hyperbolic spac...
متن کاملHomomorphisms on Topological Groups from the Perspective of Bourbaki-boundedness
In this note we study some topological properties of bounded sets and Bourbaki-bounded sets. Also we introduce two types of Bourbaki-bounded homomorphisms on topological groups including, n$-$Bourbaki-bounded homomorphisms and$hspace{1mm}$ B$-$Bourbaki-bounded homomorphisms. We compare them to each other and with the class of continuous homomorphisms. So, two topologies are presented on them a...
متن کاملCommensurating Endomorphisms of Acylindrically Hyperbolic Groups and Applications
We prove that the outer automorphism group Out(G) is residually finite when the group G is virtually compact special (in the sense of Haglund and Wise) or when G is isomorphic to the fundamental group of some compact 3-manifold. To prove these results we characterize commensurating endomorphisms of acylindrically hyperbolic groups. An endomorphism φ of a group G is said to be commensurating, if...
متن کاملSouslin measurable homomorphisms of topological groups
1. In a recent paper [18], A. Kleppner proved that every Haar measurable homomorphism 4 : G ~ H between locally compact groups G, H is continuous. This result also follows from a measure theoretic result by D. H. Fremlin [8], (see also [9, 19]), which provides a technique to prove measurability of uncountable unions of measurable sets. The purpose of this note is to present a different and new ...
متن کاملCategorically Proper Homomorphisms of Topological Groups
We extend the Dikranjan-Uspenskij notions of c-compact and h-complete topological group to the morphism level, study the stability properties of the newly defined types of maps, such as closure under direct products, and compare them with their counterparts in topology. We assume Hausdorffness only when our proofs require us to do so, which leads to new results and the affirmation of some facts...
