Generalised quadratic forms and the u-invariant [PDF]
The u-invariant of a field is the supremum of the dimensions of anisotropic quadratic forms over the field. We define corresponding u-invariants for hermitian and generalised quadratic forms over a division algebra with involution in characteristic 2 and

Real Gel'fand-Mazur division algebras
We show that the complexification (A˜,τ˜) of a real locally pseudoconvex (locally absorbingly pseudoconvex, locally multiplicatively pseudoconvex, and exponentially galbed) algebra (A,τ) is a complex locally pseudoconvex (resp., locally absorbingly ...

A Combinatorial Discussion on Finite Dimensional Leavitt Path Algebras [PDF]
Any finite dimensional semisimple algebra A over a field K is isomorphic to a direct sum of finite dimensional full matrix rings over suitable division rings.

On maximal immediate extensions of valued division algebras [PDF]
We show an extension theorem for strictly contracting bilinear mappings into a spherically complete valued vector space and we apply this result to prove that every maximal valued division algebra having the same characteristic as its residue division ...

Admissible groups, symmetric factor sets, and simple algebras
Let K be a field of characteristic zero and suppose that D is a K-division algebra; i.e. a finite dimensional division algebra over K with center K. In Mollin [1] we proved that if K contains no non-trivial odd order roots of unity, then every finite odd

Dixon-Rosenfeld lines and the Standard Model
We present three new coset manifolds named Dixon-Rosenfeld lines that are similar to Rosenfeld projective lines except over the Dixon algebra $$\mathbb {C}\otimes \mathbb {H}\otimes \mathbb {O}$$ C ⊗ H ⊗ O .

Enveloping algebras of Malcev algebras [PDF]
We first discuss the construction by Perez-Izquierdo and Shestakov of universal nonassociative enveloping algebras of Malcev algebras. We then describe recent results on explicit structure constants for the universal enveloping algebras (both ...

Correspondences Between Valued Division Algebras and Graded Division Algebras
Let \(D\) be a finite-dimensional central division algebra over a field \(F\) with a Henselian valuation \(v_F\). The valuation \(v_F\) extends to a (Schilling) valuation \(v_D\) on \(D\), and there is an associated graded ring \(GD=\bigoplus_{\gamma\in\Gamma_D}GD_\gamma\), where \(\Gamma_D\) is the value group of \(v_D\) and, for \(\gamma\in\Gamma_D\),

On Gelfand-Mazur theorem on a class of F-algebras
A topological algebra A is said to be fundamental if there exists b > 1 such that for every sequence(xn) in A, (xn) is Cauchy whenever the sequence bn(xn − xn-1) tends to zero as n → ∞.
