Projective Essential Idempotents [PDF]
IEEE Transactions on Information Theory, 2023 This paper introduces the concept of projective essential idempotents. These are primitive central idempotents in a twisted group algebra. The first main result provides conditions for the existence of them. In the second main result, we prove that every $q$-ary simplex code can be seen as an ideal of a twisted group algebra generated by a projective ...

Idempotents, free products and quandle coverings [PDF]
, 2022 In this paper, we investigate idempotents in quandle rings and relate them with quandle coverings. We prove that integral quandle rings of quandles of finite type that are non-trivial coverings over nice base quandles admit infinitely many non-trivial ...

Rings with transitive chaining of idempotents [PDF]
, 2023 International audienceWe prove that transitivity of strong or weak 2-chaining of idempotents is equivalent to centrality of idempotents modulo the Jacobson ...

Smarandache Idempotents infinite ring Zn and in Group Ring ZnG [PDF]
, 2005 This paper has 4 sections. In section 1, we just give the basic definition of S-idempotents in rings. In section 2, we prove the existence of S-idempotents in the ring Zn where n = 2mp;m 2 N and p is an odd ...

Every group is a maximal subgroup of the free idempotent generated semigroup over a band [PDF]
, 2013 Given an arbitrary group G we construct a semigroup of idempotents (band) BG with the property that the free idempotent generated semigroup over BG has a maximal subgroup isomorphic to G. If G is finitely presented then BG is finite. This answers several

(ℓ,p)-Jones-Wenzl idempotents [PDF]
, 2022 The Jones-Wenzl idempotents of the Temperley-Lieb algebra are celebrated elements defined over characteristic zero and for generic loop parameter. Given a pointed field ( R , δ ) , we extend the existing results of Burrull, Libedinsky and Sentinelli to ...

Maximal subgroups of free idempotent-generated semigroups over the full transformation monoid [PDF]
, 2011 Let Tn be the full transformation semigroup of all mappings from the set {1, . . . , n} to itself under composition. Let E = E(Tn) denote the set of idempotents of Tn and let e ∈ E be an arbitrary idempotent satisfying |im (e)| = r ≤ n − 2. We prove that

Idempotents in nest algebras [PDF]
, 1991 The algebraic equivalence and similarity classes of idempotents within a nest algebra Alg β are completely characterized. We obtain necessary and sufficient conditions for two idempotents to be equivalent or similar.
