Analysis of endomorphisms [PDF]
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

Orienteering with One Endomorphism. [PDF]
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 ...

Strings of group endomorphisms [PDF]
Recently the strings and the string number of self-maps were used in the computation of the algebraic entropy of specific abelian group endomorphisms. We introduce two special kinds of strings, and their relative string numbers.

Endomorphisms of the Cuntz algebras [PDF]
This mainly expository article is devoted to recent advances in the study of dynamical aspects of the Cuntz algebras O_n, n<infty, via their automorphisms and, more generally, endomorphisms.

Endomorphism Breaking in Graphs [PDF]
We introduce the endomorphism distinguishing number $D_e(G)$ of a graph $G$ as the least cardinal $d$ such that $G$ has a vertex coloring with $d$ colors that is only preserved by the trivial endomorphism. This generalizes the notion of the distinguishing number $D(G)$ of a graph $G$, which is defined for automorphisms instead of endomorphisms.As the ...

On Stability of Endomorphisms [PDF]
In this note we prove a generalization of R. Mañé’s theorem. R. Mañé proved that C r

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 EXOTIC MODELS [PDF]
AbstractWe calculate the endomorphism dga of Franke's exotic algebraic model for the K-local stable homotopy category at odd primes. We unravel its original abstract structure to give explicit generators, differentials and products.

On endomorphisms of a solenoid [PDF]
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.
