Irreducibility of a free group endomorphism is a mapping torus invariant [PDF]
Commentarii Mathematici Helvetici, 2019 We prove that the property of a free group endomorphism being irreducible is a group invariant of the ascending HNN extension it defines. This answers a question posed by Dowdall-Kapovich-Leininger.

On endomorphisms of a solenoid [PDF]
Proceedings 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.

ENDOMORPHISMS OF EXOTIC MODELS [PDF]
Glasgow Mathematical Journal, 2018 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.

Semi-group structure of all endomorphisms of a projective variety admitting a polarized endomorphism [PDF]
, 2018 Let $X$ be a projective variety admitting a polarized (or more generally, int-amplified) endomorphism. We show: there are only finitely many contractible extremal rays; and when $X$ is $\mathbb{Q}$-factorial normal, every minimal model program is ...

Computing endomorphism rings and Frobenius matrices of Drinfeld modules [PDF]
Journal of Number Theory, 2019 Let $\mathbb{F}_q[T]$ be the polynomial ring over a finite field $\mathbb{F}_q$. We study the endomorphism rings of Drinfeld $\mathbb{F}_q[T]$-modules of arbitrary rank over finite fields.

On the Brauer Class of Modular Endomorphism Algebras [PDF]
In this paper we study the Brauer class of the endomorphism algebra Xf of the motive attached to a primitive elliptic modular cusp form f without complex multiplication (CM).

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.

Computing the geometric endomorphism ring of a genus-2 Jacobian [PDF]
Mathematics of Computation, 2016 We describe an algorithm, based on the properties of the characteristic polynomials of Frobenius, to compute $\operatorname{End}_{\overline{K}}(A)$ when $A$ is the Jacobian of a nice genus-2 curve over a number field $K$. We use this algorithm to confirm

Trace Ideals and Centers of Endomorphism Rings of Modules over Commutative Rings [PDF]
, 2016 Let $R$ be a commutative Noetherian ring and $M$ a finitely generated $R$-module. Under various hypotheses, it is proved that the center of $\mbox{End}_R(M)$ coincides with the endomorphism ring of the trace ideal of $M$.
