Subalgebras of Bigraded Koszul Algebras

چکیده
We show that diagonal subalgebras and generalized Veronese subrings of a bigraded Koszul algebra are Koszul. We give upper bounds for the regularity of sidediagonal and relative Veronese modules and apply the results to symmetric algebras and Rees rings.

On I-null Lie Algebras
We consider the class of complex Lie algebras for which the Koszul 3-form is zero, and prove that it contains all quotients of Borel subalgebras, or of their nilradicals, of finite dimensional complex semisimple Lie algebras. A list of Kac-Moody types for indecomposable nilpotent complex Lie algebras of dimension ≤ 7 is given.
متن کاملLimits of Algebras with Shifting and a Relationship between the Mod Two Steenrod and Dyer-lashof Algebras
We provide a construction, refined from an inverse limit, that produces the mod 2 Steenrod and Dyer-Lashof algebras from each other. In fact, the construction relates various subalgebras and quotients of the universal Steenrod algebra of operations for H∞-ring spectra. We also describe how the construction transforms the axiomatic properties of homogeneous pre-Koszul algebras and Poincaré-Birkh...
متن کاملREDEFINED FUZZY SUBALGEBRAS OF BCK/BCI-ALGEBRAS
Using the notion of anti fuzzy points and its besideness to and nonquasi-coincidence with a fuzzy set, new concepts in anti fuzzy subalgebras in BCK/BCI-algebras are introduced and their properties and relationships are investigated.
متن کاملA New Approach to the Koszul Property in Representation Theory Using Graded Subalgebras
Given a quasi-hereditary algebra B, we present conditions which guarantee that the algebra gr B obtained by grading B by its radical filtration is Koszul and at the same time inherits the quasi-hereditary property and other good Lie-theoretic properties that B might possess. The method involves working with a pair (A, a) consisting of a quasi-hereditary algebra A and a (positively) graded subal...
متن کاملSome remarks about the second Leibniz cohomology group for Lie algebras
We compare by a very elementary approach the second adjoint and trivial Leibniz cohomology spaces of a Lie algebra to the usual ones. Examples are given of coupled cocycles. Some properties are deduced as to Leibniz deformations. We also consider the class of Lie algebras for which the Koszul 3-form is zero, and prove that it contains all quotients of Borel subalgebras, or of their nilradicals,...
