Endomorphisms and automorphisms of the shift dynamical system
Mathematical Systems Theory, 1969Let \((X(g),a)\) 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 \(\mathcal S\).

Textile systems and one-sided resolving automorphisms and endomorphisms of the shift
Ergodic Theory and Dynamical Systems, 2008AbstractTwo results on textile systems are obtained. Using these we prove that for any automorphism φ of any topologically-transitive subshift of finite type, if φ is expansive and φ or φ−1 has memory zero or anticipation zero, then φ is topologically conjugate to a subshift of finite type.

A determinant for automorphisms of groups
Communications in Algebra, 2022Let H and K be groups. In this paper we introduce a concept of determinant for endomorphisms of H × K and some concepts of incompatibility for group pairs as a measure of how far H and K are from being isomorphic.

Automorphic and endomorphic reducibility and primitive endomorphisms of free metabelian groups
Communications in Algebra, 1997Let 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
