Endomorphism Type of P(3m + 1,3) [PDF]
Mathematics, 2023 There are six different classes of endomorphisms for a graph. The sets of these endomorphisms always form a chain under the inclusion of sets. In order to study these different endomorphisms more systematically, Böttcher and Knauer proposed the concept ...

Mass endomorphism and spinorial Yamabe type problems on conformally flat manifolds [PDF]
Communications in Analysis and Geometry, 2006 Let M be a compact manifold equipped with a Riemannian metric g and a spin structure \si. We let $\lambda (M,[g],\si)= \inf_{\tilde{g} \in [g]} \lambda_1^+(\tilde{g}) Vol(M,\tilde{g})^{1/n}$ where $\lambda_1^+(\tilde{g})$ is the smallest positive ...

Cantor Type Basic Sets of Surface $A$-endomorphisms [PDF]
Nelineinaya Dinamika, 2021 The paper is devoted to an investigation of the genus of an orientable closed surface $M^{2}$ which admits $A$-endomorphisms whose nonwandering set contains a one-dimensional strictly invariant contracting repeller $\Lambda_{r}$ with a uniquely defined unstable bundle and with an admissible boundary of finite type. First, we prove that, if $M^{2}$ is a

Quotients of Torus Endomorphisms and Lattès-Type Maps [PDF]
Arnold Mathematical Journal, 2020 AbstractWe show that if an expanding Thurston map is the quotient of a torus endomorphism, then it has a parabolic orbifold and is a Lattès-type map.

Endomorphism regular Ockham algebras of finite Boolean type [PDF]
Glasgow Mathematical Journal, 1997 AbstractIf (L; ƒ) is an Ockham algebra with dual space (X; g), then it is known that the semigroup of Ockham endomorphisms onLis (anti-)isomorphic to the semigroup Λ(X; g) of continuous order-preserving mappings onXthat commute withg. Here we consider the case whereLis a finite boolean lattice and ƒ is a bijection. We begin by determining the size of Λ(

Canonical extension of endomorphisms of type III factors [PDF]
American Journal of Mathematics, 2003 We extend the notion of the canonical extension of automorphisms of type III factors to the case of endomorphisms with finite statistical dimensions. Following the automorphism case, we introduce two notions for endomorphisms of type III factors: modular endomorphisms and Connes-Takesaki modules. Several applications to compact groups of automorphisms

Endomorphisms of Artin groups of typeD [PDF]
Algebraic & Geometric TopologyIn this paper we determine a classification of the endomorphisms of the Artin group $A [D_n]$ of type $D_n$ for $n\ge 6$. In particular we determine its automorphism group and its outer automorphism group. We also determine a classification of the homomorphisms from $A[D_n]$ to the Artin group $A [A_{n-1}]$ of type $A_{n-1}$ and a classification of the

Toeplitz Algebras of Correspondences and Endomorphisms of Sums of Type I Factors [PDF]
Michigan Mathematical Journal, 2020 It is a well-known fact that endomorphisms of $B(H)$ are intimately connected with families of mutually orthogonal isometries, i.e. with representations of the so-called Toeplitz $C^*$-algebras. In this paper we consider a natural generalization of this connection between the representation theory of certain $C^*$-algebras associated to graphs and ...
