A note on the cohomology of moduli spaces of local shtukas
Bulletin of the London Mathematical Society, Volume 57, Issue 12, Page 3709-3729, December 2025.Abstract We study localized versions of spectral action of Fargues–Scholze, using methods from higher algebra. As our main motivation and application, we deduce a formula for the cohomology of moduli spaces of local shtukas under certain genericity assumptions, and discuss its relation with the Kottwitz conjecture.

End-regular and End-orthodox generalized lexicographic products of bipartite graphs
Open Mathematics, 2016 A graph X is said to be End-regular (End-orthodox) if its endomorphism monoid End(X) is a regular (orthodox) semigroup. In this paper, we determine the End-regular and the End-orthodox generalized lexicographic products of bipartite graphs.

On geometry of sub-Riemannian η-Einstein manifolds
Дифференциальная геометрия многообразий фигур, 2019 On a sub-Riemannian manifold of contact type a connection with torsion is considered, called in the work a Ψ-connection. A Ψ-connection is a particular case of an N-connection.

On (σ, δ)(S, 1) rings and their extensions [PDF]
Mathematica Moravica, 2017 Let R be a ring, σ an endomorphism of R and δ a σ derivation of R. We recall that R is called an (S, 1)-ring if for a, b _ R, ab = 0 implies aRb = 0. We involve σ and δ to generalize this notion and say that R is a (σ, δ) - (S, 1) ring if for a, b _ R ...

End-regularity of generalized bicycle graph
AKCE International Journal of Graphs and Combinatorics, 2020 A graph G is called End-regular, if every endomorphism of G is regular as a monoid. In this article, we investigate End-regularity of bicycle graphs.

On the Multidimensional Limit Theorem for Endomorphisms of the Euclidean Space [PDF]
Учёные записки Казанского университета: Серия Физико-математические науки, 2015 Nearly optimal refinement of the earlier estimates of the convergence rate in the multidimensional central limit theorem for sums of functions of the trajectories of endomorphisms of the s-dimensional Euclidean space was performed.

Ordered Structures and Projections
International Journal of Mathematics and Mathematical Sciences, 2008 We associate a covering relation to the usual order relation defined in the set of all idempotent endomorphisms (projections) of a finite-dimensional vector space. A characterization is given of it.

International Journal of Mathematics and Mathematical Sciences, 2016 We introduce the notion of fq-derivation as a new derivation of G-algebra. For an endomorphism map f of any G-algebra X, we show that at least one fq-derivation of X exists. Moreover, for such a map, we show that a self-map dqf of X is fq-derivation of X

Properly stratified endomorphism algebras
Journal of Algebra, 2005 The authors prove the following statement: Theorem. Let \(R\) be a commutative, local, self-injective algebra over an algebraically closed field. Let \({\mathcal X}=\{X(1)=R,X(2),\dots,X(n)\}\) be a sequence of local-colocal \(R\)-modules reflecting inclusions of the corresponding local ideals \(\underline X(i)\) of \(R\) (i.e. \(\underline X(i)\subset\
