On Root Arrangements of Polynomial-Like Functions and their Derivatives

Kostov, Vladimir (2005)

Serdica Mathematical Journal

2000 Mathematics Subject Classification: 12D10.We show that for n = 4 they are realizable either by hyperbolic polynomials of degree 4 or by non-hyperbolic polynomials of degree 6 whose fourth derivatives never vanish (these are a particular case of the so-called hyperbolic polynomial-like functions of degree 4).

On ruled fields

Jack Ohm (1989)

Journal de théorie des nombres de Bordeaux

Some results and problems that arise in connection with the foundations of the theory of ruled and rational field extensions are discussed.

On stable polynomials

Miloslav Nekvinda (1989)

Aplikace matematiky

The article is a survey on problem of the theorem of Hurwitz. The starting point of explanations is Schur's decomposition theorem for polynomials. It is showed how to obtain the well-known criteria on the distribution of roots of polynomials. The theorem on uniqueness of constants in Schur's decomposition seems to be new.

On ternary semifields

Tapan K. Dutta, Sukhendu Kar (2004)

Discussiones Mathematicae - General Algebra and Applications

In this paper, we introduce the notion of ternary semi-integral domain and ternary semifield and study some of their properties.In particular we also investigate the maximal ideals of the ternary semiring Z¯₀.
