Endomorphism Algebras of 2-term Silting Complexes
, 2016We study possible values of the global dimension of endomorphism algebras of 2-term silting complexes. We show that for any algebra A whose global dimension gl.dim A ≤ 2 and any 2-term silting complex P in the bounded derived category Db(A) of A, the ...

Enumerating submodules invariant under an endomorphism
, 2016We study zeta functions enumerating submodules invariant under a given endomorphism of a finitely generated module over the ring of (S-)integers of a number field.

In previous chapters we have already studied eigenvalues and eigenvectors of matrices. In this chapter we generalize these concepts to endomorphisms, and we investigate when endomorphisms on finite dimensional vector spaces can be represented by diagonal matrices or (upper) triangular matrices. From such representations we easily can read off important

Anti-endomorphisms and endomorphisms satisfying an Engel condition
Communications in Algebra, 2019AbstractLet R be a semiprime ring with τ an anti-endomorphism or endomorphism. It is proved that if τ satisfies an Engel condition [[…[[xτ,xn1],xn2]…],xnk]=0 for all x∈R, where n1,n2,…,nk are k fixed positive integers, then τ is a commuting map (i.e. [xτ,x]=0 for all x∈R).

Since there are usually lots of endomorphisms in a BA, the variations of this function under algebraic operations have not been studied much. Its main relationships to our other functions are the following two easily established facts: |UltA| ≤ |EndA| and |AutA| ≤ |EndA|.
