We generalize Amitsur's construction of central simple algebras over a field F which are split by field extensions possessing a derivation with field of constants F to nonassociative algebras: for every central division algebra D over a field F of ch...

How to obtain lattices from (f,?,?)-codes via a generalization of Construction A (2017)
Journal Article

We show how cyclic (f,?,?)-codes over finite rings canonically induce a Z-lattice in RN by using certain quotients of orders in nonassociative division algebras defined using the skew polynomial f. This construction generalizes the one using certain... Read More about How to obtain lattices from (f,?,?)-codes via a generalization of Construction A.

Finite nonassociative algebras obtained from skew polynomials and possible applications to (f, σ, δ)-codes (2017)
Journal Article
Pumpluen, S. (2017). Finite nonassociative algebras obtained from skew polynomials and possible applications to (f, σ, δ)-codes. Advances in Mathematics of Communications, 11(3), 615-634. https://doi.org/10.3934/amc.2017046

Let S be a unital ring, S[t; σ, δ] a skew polynomial ring where σ is an injective endomorphism and δ a left σ -derivation, and suppose f ε S[t; σ, δ] has degree m and an invertible leading coefficient. Using right division by f to define the multipl... Read More about Finite nonassociative algebras obtained from skew polynomials and possible applications to (f, σ, δ)-codes.

Let ? be an automorphism of a field K with fixed field F. We study the automorphisms of nonassociative unital algebras which are canonical generalizations of the associative quotient algebras K[t; ?]=fK[t; ?] obtained when the twisted polynomialf 2 K...

Nonassociative differential extensions of characteristic p (2017)
Journal Article
Pumpluen, S. (2017). Nonassociative differential extensions of characteristic p. Results in Mathematics, 72(1-2), https://doi.org/10.1007/s00025-017-0656-x

Let F be a field of characteristic p. We define and investigate nonassociative differential extensions of F and of a finite-dimensional central division algebra over F and give a criterium for these algebras to be division. As special cases, we obtai... Read More about Nonassociative differential extensions of characteristic p.
