Orienteering with One Endomorphism. [PDF]
Mathematica (N Y), 2023 AbstractIn supersingular isogeny-based cryptography, the path-finding problem reduces to the endomorphism ring problem. Can path-finding be reduced to knowing just one endomorphism? It is known that a small degree endomorphism enables polynomial-time path-finding and endomorphism ring computation (in: Love and Boneh, ANTS XIV-Proceedings of the ...

Endomorphisms of fibred groups [PDF]
Proceedings of the Edinburgh Mathematical Society, 1989 A collection = {Gα|α∈A} of proper subgroups Gα of a group G is a fibration of G ifIt is of geometric interest to associate two semigroups to a group G with fibration :

Yang–Baxter endomorphisms [PDF]
Journal of the London Mathematical Society, 2020 Every unitary solution of the Yang-Baxter equation (R-matrix) in dimension $d$ can be viewed as a unitary element of the Cuntz algebra ${\mathcal O}_d$ and as such defines an endomorphism of ${\mathcal O}_d$. These Yang-Baxter endomorphisms restrict and extend to endomorphisms of several other $C^*$- and von Neumann algebras and furthermore define a II$

Some Classification Theorems and Endomorphisms in New Classes
Mathematics, 2023 Let ℧ be a prime ring of char(℧) ≠2 with its center Z. This article introduces new classes of endomorphisms and investigates how they relate to antiautomorphisms of prime rings and the commutativity of prime rings.

Analysis of endomorphisms [PDF]
Journal of Physics: Conference Series, 2012 In this expository article, we discuss the recent progress in the study of endomorphisms and automorphisms of the Cuntz algebras and, more generally graph C* -algebras (or Cuntz-Krieger algebras). In particular, we discuss the definition and properties of both the full and the restricted Weyl group of such an algebra.

Geometric 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.

Endomorphisms of Some Groupoids of Order $k+k^2$
Известия Иркутского государственного университета: Серия "Математика", 2020 Automorphisms and endomorphisms are actively used in various theoretical studies. In particular, the theoretical interest in the study of automorphisms is due to the possibility of representing elements of a group by automorphisms of a certain algebraic ...

Shimura subvarieties via endomorphisms
Comptes Rendus. Mathématique, 2022 We prove that there exist two families in $\mathcal{M}_2, \mathcal{M}_3$ of non-Galois covers of the projective line whose Jacobians trace out Shimura subvarieties of $\mathcal{A}_2, \mathcal{A}_3$. They provide the first two explicit examples of Shimura

Generalized derivations and generalized exponential monomials on hypergroups [PDF]
Opuscula Mathematica, 2023 In one of our former papers "Endomorphisms of the measure algebra of commutative hypergroups" we considered exponential monomials on hypergroups and higher order derivations of the corresponding measure algebra.
