On endomorphisms of a solenoid [PDF]

open access: yesProceedings of the American Mathematical Society, 1976
Geometrically simple Bernoulli generators are constructed for certain ergodic endomorphisms of solenoids. An arbitrary ergodic solenoidal group automorphism is obtained as the limit of a sequence of such Bernoulli factors and hence, by a theorem of D. S. Ornstein, must be measure-theoretically isomorphic to a Bernoulli shift.

On the R-automorphisms of formal power series on several indeterminates and with coefficients over the ring R

open access: yesSelecciones Matemáticas, 2022
In this paper, we show a way to characterize the R-automorphisms of formal power series on several indeterminates and with coefficients over a commutative ring with identity, R.

Minkowski Endomorphisms [PDF]

open access: yesGeometric and Functional Analysis, 2017
Several open problems concerning Minkowski endomorphisms and Minkowski valuations are solved. More precisely, it is proved that all Minkowski endomorphisms are uniformly continuous but that there exist Minkowski endomorphisms that are not weakly-monotone. This answers questions posed repeatedly by various authors.

Explicit CM-theory for level 2-structures on abelian surfaces [PDF]

open access: yes, 2011
For a complex abelian variety $A$ with endomorphism ring isomorphic to the maximal order in a quartic CM-field $K$, the Igusa invariants $j_1(A), j_2(A),j_3(A)$ generate an abelian extension of the reflex field of $K$.

Unicyclic Graphs Whose Completely Regular Endomorphisms form a Monoid

open access: yesMathematics, 2020
In this paper, completely regular endomorphisms of unicyclic graphs are explored. Let G be a unicyclic graph and let c E n d ( G ) be the set of all completely regular endomorphisms of G.

On the trace of permuting tri-derivations on rings

open access: yesМатематичні Студії, 2022
In the paper we examined the some effects of derivation, trace of permuting tri-derivation and endomorphism on each other in prime and semiprime ring. Let $R$ be a $2,3$-torsion free prime ring and $F:R\times R\times R\rightarrow R$ be a permuting tri ...

Retractions and S-endomorphisms

open access: yesSemigroup Forum, 1974
A map f: S ÷ S where S is a semigroup is a retraction if and only if f2 = f, f is a semigroup homomorphism, and f(S) is a two-slded ideal of S. A map f: S ÷ S is a right S-endomorphism if and only if f(xy) = f(x)y for all x,y ~ S. Note that right S-endomorphlsms are also called left translations. It is well-known ([2], [3]) that when S is a semilattice

$p$-adic Berglund-H\"ubsch Duality [PDF]

open access: yes, 2014
Berglund-H\"ubsch duality is an example of mirror symmetry between orbifold Landau-Ginzburg models. In this paper we study a D-module-theoretic variant of Borisov's proof of Berglund-H\"ubsch duality.
