Endomorphisms of Fraïssé limits and automorphism groups of algebraically closed relational structures

, 2012
Let Ω be the Fraïssé limit of a class of relational structures. We seek to answer the following semigroup theoretic question about Ω. What are the group H-classes, i.e. the maximal subgroups, of End(Ω)? Fraïssé limits for which we answer this question include the random graph R, the random directed graph D, the random tournament T, the random bipartite

Endomorphisms and automorphisms of the shift dynamical system

Mathematical Systems Theory, 1969
Let \((X(g),a)\) be the shift dynamical system, where the phase space \(X(g)\) of this system is the set of all bisequences over a finite symbol set \(\mathcal S\) with \(\mathrm{card }g>1\). The topology of \(X(g)\) is the product topology induced by the discrete topology of \(\mathcal S\).

Endomorphisms and Automorphisms for Factor Inclusions

1993
We investigate some kinds of *;-endomorphisms and automorphisms for inclusions of type II1 factors in connection with Jones index theory.

Automorphic and endomorphic reducibility and primitive endomorphisms of free metabelian groups

Communications in Algebra, 1997
Let S be the free metabelian group of rank 2. In this paper we prove the following results:(i) Given a pair of elements g, h of S, there exists an algorithm to decide whether or not g is an automorphic image of h; (ii) If g, h are in the commutator subgroup S′ of S such that each is an endomorphic image of the other then g , h are automorphic; (iii) If
