Let F be a field of characteristic 0, E be the unitary infinite dimensional Grassmann algebra over F and consider the algebra M1,1E with its natural Z2-grading. We describe the graded A-identities ...

Minimum degree of an A-identity of E ⊗ E

Autor: Humberto Luiz Talpo, Fernando Augusto Naves

Publikováno v: International Journal of Algebra and Computation. 30:1237-1256

Let [Formula: see text] be a field of characteristic zero, algebraically closed and [Formula: see text] be the unitary infinite-dimensional Grassmann [Formula: see text]-algebra. Our aim is to determine the minimal degree of an [Formula: see text]-po

Gradings on Incidence Algebras and their Graded Polynomial Identities

Autor: Humberto Luiz Talpo, Waldeck Schützer

Let P a locally finite partially ordered set, F a field, G a group, and I(P,F) the incidence algebra of P over F. We describe all the inequivalent elementary G-gradings on this algebra. If P is bounded, F is a infinite field of characteristic zero, a

On Ideals That Are Closed Under Continuous Endomorphisms

Autor: Dimas José Gonçalves, Humberto Luiz Talpo, Waldeck Schützer

Publikováno v: Communications in Algebra. 44:2583-2591

Let 𝔽 be the field ℝ or ℂ, and let 𝔽 ⟨ X ⟩ be the free associative algebra generated by the infinite set X. If f ∈ 𝔽 ⟨ X ⟩, define its norm ‖f‖ as the sum of the absolute value of its coefficients. We describe the ideals of

A-identities for the $${2 \times 2}$$ 2 × 2 matrix algebra

Autor: Dimas José Gonçalves, Humberto Luiz Talpo, Waldeck Schützer

Publikováno v: Archiv der Mathematik. 106:417-429

Let K be an algebraically closed field of characteristic zero. We prove that the minimum degree for A-identities of ${M_{2}(K)}$ is 6. We also construct an explicit A-polynomial of degree 6 and prove it is an A-identity.

Covering number for reflections in trees

Autor: Humberto Luiz Talpo, Marcelo Firer

Publikováno v: Journal of Group Theory. 11

We define a reflection in a tree as an involutive automorphism whose set of fixed points is a geodesic and prove that, for the case of a homogeneous tree of even degree, the group of even automorphisms may be covered by at most 11 reflections. Reflec

As sequências espectrais foram criadas por Jean Leray num campo de concentração durante a Segunda Guerra Mundial motivado por problemas inerentes à Topologia Algébrica. Num primeiro momento, surge como uma ferramenta para auxiliar no cálculo da
