3-Bihom-ρ-Lie Algebras, 3-Pre-Bihom-ρ-Lie Algebras

The purpose is to introduce the notions of 3-Bihom-ρ-Lie algebras and 3-preBihom-ρ-Lie algebras. The authors describe their constructions and express the related lemmas and theorems. Also, they define the 3-Bihom-ρ-Leibniz algebras and show that a3-Bihom-ρ-Lie algebra is a 3-Bihom-ρ-Leibniz algebra with the ρ-Bihom-skew symmetry property. Moreover, a combination of a 3-Bihom-ρ-Lie algebra bracket and a Rota-Baxer operator gives a 3-pre-Bihom-ρ-Lie algebra structure.

Additive Lie (ξ-Lie) Derivations and Generalized Lie (ξ-Lie) Derivations on Prime Algebras

The additive(generalized)ξ-Lie derivations on prime algebras are characterized. It is shown, under some suitable assumptions, that an additive map L is an additive generalized Lie derivation if and only if it is the sum of an additive generalized derivation and an additive map from the algebra into its center vanishing all commutators; is an additive(generalized)ξ-Lie derivation with ξ = 1 if and only if it is an additive(generalized)derivation satisfying L(ξA)= ξL(A)for all A. These results are then used to characterize additive(generalized)ξ-Lie derivations on several operator algebras such as Banach space standard operator algebras and von Neumman algebras.

△-tame quasi-hereditary algebras

Let (K, M,H) be an upper triangular bimodule problem. Briistle and Hille showed that the opposite algebra A of the endomorphism algebra of a projective generator P of the matrices category of (K., M, H) is quasi-hereditary, and there is an equivalence between the category of△-good modules of A and Mat(K, M). In this note, based on the tame theorem for bimodule problems, we show that if the algebra A associated with an upper triangular bimodule problem is of△-tame representation type, then the category F(△) has the homogeneous property, i.e. almost all modules in F(△) are isomorphic to their Auslander-Reiten translations. Moreover, if (K, M,H)is an upper triangular bipartite bimodule problem, then A is of△-tame representation type if and only if F(△) is homogeneous.

Derivations,automorphisms, and representations of complex ω-Lie algebras

Let (𝔤,ω) be a finite-dimensional non-Lie complex ω-Lie algebra. We study the derivation algebra Der(𝔤) and the automorphism group Aut(𝔤) of (𝔤,ω). We introduce the notions of ω-derivations and ω-automorphisms of (𝔤,ω) which naturally preserve the bilinear form ω. We show that the set Der_ω(𝔤) of all ω-derivations is a Lie subalgebra of Der(𝔤) and the set Aut_ω(𝔤) of all ω-automorphisms is a subgroup of Aut(𝔤). For any three-dimensional and four-dimensional nontrivial ω-Lie algebra 𝔤, we compute Der(𝔤) and Aut(𝔤) explicitly, and study some Lie group properties of Aut(𝔤). We also study representation theory of ω-Lie algebras. We show that all three-dimensional nontrivial ω-Lie algebras are multiplicative, as well as we provide a four-dimensional example of ω-Lie algebra that is not multiplicative. Finally, we show that any irreducible representation of the simple ω-Lie algebra C_α(α≠0,?1) is one-dimensional.

Cohen–Macaulay Auslander algebras of skewed-gentle algebras

For any skewed-gentle algebra, we characterize its indecomposable Gorenstein projective modules explicitly and describe its Cohen–Macaulay Auslander algebra. We prove that skewed-gentle algebras are always Gorenstein, which is independent of the characteristic of the ground field, and the Cohen–Macaulay Auslander algebras of skewed-gentle algebras are also skewed-gentle algebras.
