Endomorphisms of Leavitt Path Algebras
… path algebra, and producing methods to construct endomorphisms of Leavitt path algebras that take a given maximal abelian subalgebra (MASA) to the diagonal.

Dynamics of irreducible endomorphisms of F_n
We consider the class non-surjective irreducible endomorphisms of the free group F_n. We show that such an endomorphism \phi is topologically represented by a simplicial immersion f:G \rightarrow G of a marked graph G; along the way we classify the dynamics of \partial \phi acting on \partial F_n: …

Computing congruences and endomorphisms for algebras of type (2m, 1n)
… objetivo da package CREAM (Algebra CongRuences, Endomorphisms and AutomorphisMs) é resolver esta situação implementando algoritmos eficientes para calcular congruências, endomorfismos e automorfismos de álgebras do tipo (2m, 1 n). Vários algoritmos gerais (como em [15]) serão adaptados para o …

Uniqueness of p-local truncated Brown-Peterson spectra
… classes in the Adams spectral sequence for endomorphisms of BP⟨n⟩. We also prove that there are enough endomorphisms of BP⟨n⟩ in a suitable sense. When p = 2, we obtain the results for n ≤ 3.

Categories with projective functors
… the description of the algebra of adjoint finite endomorphisms of a simple module with minimal annihilator over a semi-simple Lie algebra and the (rough) structure of parabolically induced modules.

A q-analogue of spanning trees : nilpotent transformations over finite fields
… and spanning trees. For example, nilpotent endomorphisms on an n-dimensional vector space over Fq is a q-analogue of rooted spanning trees of the complete graph Kn. This relationship is based on two similar bijective proofs to calculate the number of spanning trees and nilpotent …

On the topological entropy of nilpotent groups of finite rank
… small values of topological entropy for their endomorphisms. Then we investigate a more general case of nilpotent periodic locally compact p-groups, reducing the computations to maximal p-subgroups. The role of p-groups becomes somehow fundamental, so we focus on locally compact Heisenberg …

Exploring the multiplicative structure of Z/nZ
… insight into the actions, semidirect products, endomorphisms, and automorphisms associated with such monoids. Considering the set of homomorphisms of prime power multiplicative modular monoids, with the law operator of the codomain, we identify its algebraic structure as a monoid. We also …

Classification of the indecomposable finite dimensional modules of clannish algebras
… vector space equipped with a pair of idempotent endomorphisms. In contrast to Crawley-Boevey's classification, however, ours gives representations with better bases, not requiring the introduction of a fixed non-zero non-identity element of the field, and so working over the field with two …

On representations of rational Cherednik algebras
… a finite Coxeter group W with values in linear endomorphisms of an irreducible representation of W. The distribution K gives rise to an integral formula for the Gaussian inner product on a Verma module in the rational Cherednik category O. At real parameter values, the restriction of K to the …

Morita cohomology
… graded category with a single object and endomorphisms k. In the Morita model structure k is weakly equivalent to the category of perfect chain complexes over k. We define and compute derived global sections of the constant presheaf k considered as a presheaf of dg-categories with the …

Construction of Deligne Categories through ultrafilters and its applications

Positive scalar curvature and Callias-type index theorems for proper actions
… context. We construct explicit admissible endomorphisms for G-Callias-type operators from the K-theory of the Higson G-corona of M, a highly non-trivial group. The index theory developed here is applied to prove a general obstruction theorem for G- invariant metrics of positive scalar …

Langlands Duality in the Generic Fibres of Classical Hitchin Fibrations
We study L-twisted endomorphisms of holomorphic vector bundles over a compact Riemann surface. In particular, we generalise Hitchin's computation of the generic bres of the Hitchin bration to the more general L-twisted case, which presents new challenges since we lose properties intrinsic to the …

The Structure of endomorphism monoids of strong semilattices of left simple semigroups
Endomorphismenmonoide sind schon lange von Interesse in der universellen Algebra und werden für die Untersuchung bestimmter Klassen von algebraischen Strukturen eingesetzt. Für jede Algebra ist die Menge der Endomorphismen abgeschlossen unter Komposition und bildet ein Monoid (das heißt, eine …

Algebraic structure of endomorphism monoids of finite graphs
Unser Ziel in dieser Dissertation ist die Untersuchung der Beziehung zwischen der Halbgruppen-Theorie und der Graphen-Theorie. Da es bekannt ist, dass End(G) die Menge aller Endomorphismen von Graphen ein Monoid ist, konzentrieren wir uns auf die algebraischen Strukturen, wie regulär, vollständig …
