Torsion pairs via the Ziegler spectrum
Proceedings of the London Mathematical Society, Volume 133, Issue 2, August 2026.Abstract We establish a bijection between torsion pairs in the category of finite‐dimensional modules over a finite‐dimensional algebra A$A$ and pairs (Z,I)$(\mathcal {Z},\mathcal {I})$ formed by a closed rigid set Z$\mathcal {Z}$ in the Ziegler spectrum of A$A$ and a set I$\mathcal {I}$ of indecomposable injective A$A$‐modules. This is as an extension

Syntomic cohomology and real topological cyclic homology
Proceedings of the London Mathematical Society, Volume 133, Issue 2, August 2026.Abstract We define motivic filtrations on real topological Hochschild homology and its companions. In particular, we prove that real topological cyclic homology admits a natural complete filtration whose graded pieces are equivariant suspensions of syntomic cohomology.

Endomorphism rings of hyperelliptic Jacobians [PDF]
, 2005 Thesis (MSc (Mathematics))--University of Stellenbosch, 2005.The aim of this thesis is to study the unital subrings contained in associative algebras arising as the endomorphism algebras of hyperelliptic Jacobians over finite fields.

Weak ω-Approximate Biprojectivity of Banach Algebras
Journal of MathematicsFor a given Banach algebra M and a continuous endomorphism ω on M, we define weakly ω-approximately biprojective and weakly ω-approximately Helemskii biflat Banach algebras.

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 semigroups of graph endomorphisms
Discrete Mathematics, 1980 AbstractIt is shown that given a finite or infinite graph H and a subsemigroup B of its endomorphism semigroup End H, there exists a graph G such that 1.(i)|H is an induced subgraph of G,2.(ii)|H is stable by every f ϵ End G,3.(iii)|every f ϵ End G is uniquely determined by its restriction to H,4.(iv)|the restriction of End G to H is precisely B.

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.

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.

Survey on comultiplication modules [PDF]
Surveys in Mathematics and its Applications, 2019 The concept of comultiplication (as a dual notion of multiplication) modules was introduced and studied by H. Ansari-Toroghy and F. Farshadifar in 2007. This notion has obtained a great attention by many authors and now there is a considerable amount of ...

On the endomorphism monoids of Clifford semigroups
, 2018 In this paper, we study properties of the endomorphism monoids of strong semilattices of groups. In Sec. 2, several properties for endomorphism monoids of finite semilattices are investigated. In Sec.
