On a decomposition of polynomials in several variables

Andrzej Schinzel (2002)

Journal de théorie des nombres de Bordeaux

One considers representation of a polynomial in several variables as the sum of values of univariate polynomials taken at linear combinations of the variables.

On an iterated construction of irreducible polynomials over finite fields of even characteristic by Kyuregyan

Simone Ugolini (2016)

Czechoslovak Mathematical Journal

We deal with the construction of sequences of irreducible polynomials with coefficients in finite fields of even characteristic. We rely upon a transformation used by Kyuregyan in 2002, which generalizes the Q -transform employed previously by Varshamov and Garakov (1969) as well as by Meyn (1990) for the synthesis of irreducible polynomials. While in the iterative procedure described by Kyuregyan the coefficients of the initial polynomial of the sequence have to satisfy certain hypotheses, in the...

On canonical subfield preserving polynomials

Giacomo Micheli, Davide Schipani (2014)

Acta Arithmetica

Explicit monoid structure is provided for the class of canonical subfield preserving polynomials over finite fields. Some classical results and asymptotic estimates will follow as corollaries.

On ordered division rings

Ismail M. Idris (2003)

Czechoslovak Mathematical Journal

Prestel introduced a generalization of the notion of an ordering of a field, which is called a semiordering. Prestel’s axioms for a semiordered field differ from the usual (Artin-Schreier) postulates in requiring only the closedness of the domain of positivity under x x a 2 for nonzero a , instead of requiring that positive elements have a positive product. In this work, this type of ordering is studied in the case of a division ring. It is shown that it actually behaves the same as in the commutative...
