Endomorphisms of type II1-factors and Cuntz algebras [PDF]
Journal of the Australian Mathematical Society. Series A. Pure Mathematics and Statistics, 1996 AbstractAny unital *-endomorphism of a type II1-factor is implemented by isometries of a Cuntz algebra outside the factor. If the Jones index of the range of the *-endomorphism is an integer and the algebras act on the standard space, the Jones index must agree with the number of the generators of the Cuntz algebra. We also study (outer) conjugacy of *-

On the superstability of generalized d'Alembert harmonic functions
Annales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2016 The aim of this paper is to study the superstability problem of the d'Alembert type functional equation f(x+y+z)+f(x+y+σ(z))+f(x+σ(y)+z)+f(σ(x)+y+z)=4f(x)f(y)f(z) for all x,y,z ∈ G, where G is an abelian group and σ: G → G is an endomorphism such that ...

Endomorphism algebras of peak $I$-spaces over posets of infinite prinjective type [PDF]
Transactions of the American Mathematical Society, 1997 Let \(R\) be a commutative ring with an identity element and let \(I\) be a finite poset (i.e. partially ordered set) with the partial order \(\preceq\). Following the reviewer's paper [J. Pure Appl. Algebra 90, No. 1, 77-103 (1993; Zbl 0815.16006)] the authors define the category \(P(I,R)\) of peak \(I\)-spaces over the ring \(R\) to be the category ...

PRESENTING Hecke endomorphism algebras by Hasse quivers with relations [PDF]
, 2017 A Hecke endomorphism algebra is a natural generalisation of the $q$-Schur algebra associated with the symmetric group to a Coxeter group. For Weyl groups, B. Parshall, L.

Endomorphism spectra of graphs
, 1992 In this paper we give an account of the different ways to define homomorphisms of graphs. This leads to six classes of endomorphisms for each graph, which as sets always form a chain by inclusion.

Trace Ideals, Normalization Chains, and Endomorphism Rings [PDF]
, 2020 In this paper we consider reduced (non-normal) commutative noetherian rings R.With the help of conductor ideals and trace ideals of certain R-modules we deduce a criterion for a reflexive R-module to be closed under multiplication with scalars in an ...

Skew product Smale endomorphisms over countable shifts of finite type [PDF]
Ergodic Theory and Dynamical Systems, 2019 We introduce and study skew product Smale endomorphisms over finitely irreducible shifts with countable alphabets. This case is different from the one with finite alphabets and we develop new methods. In the conformal context we prove that almost all conditional measures of equilibrium states of summable Hölder continuous potentials are exact ...

The endomorphism semiring of a semilattice
, 2009 We prove that the endomorphism semiring of a nontrivial semilattice is always subdirectly irreducible and describe its monolith. The endomorphism semiring is congruence simple if and only if the semilattice has both a least and a largest ...

Monoids of ND-Full Hypersubstitutions
Discussiones Mathematicae - General Algebra and Applications, 2019 An nd-full hypersubstitution maps any operation symbols to the set of full terms of type τn. Nd-full hypersubstitutions can be extended to mappings which map sets of full terms to sets of full terms.

The endomorphism monoid of Pn¯
, 2007 In this paper, the endomorphism monoid of Pn¯, the complement of a path Pn with n vertices, is explored explicitly. It is shown that End(Pn¯) is orthodox. Some enumerative problems concerning End(Pn¯) are solved.
