Applications of integral points on elliptic curves in theory of cubic and quartic polynomials

In the following review, we introduce readers to some interesting results that have been achieved in theory of cubic and qurtic polynomials with a given discrimination....

Law of inertia for the factorization of cubic polynomials - the case of discriminants divisible by three

In this paper we extend our recent results concerning the validity of the law of inertia for the factorization of cubic polynomials over the Galois field F_p, p being a prime....

Decompositions of polynomials without real roots.

The problem of decomposition of a polynomial of degree 4 without real roots to the product of two quadratic factors is discussed in connection with the method of Cardan for solving cubic equations....

On distribution of zeros of a cubic polynomial

The paper deals with location of zeros of a cubic polynomial with general real coefficients. There are derived effective and optimal (i.e. necessary and sufficient) conditions on the coefficients of this polynomial, which e...

On the factorization of cubic polynomials with the same discriminant modulo a prime

Let Din Z and let C_D be the set of all monic cubic polynomilals with integer coefficients having a discriminant equal to D. In this paper, we devise a general method of establishing whether, for a prime p, all polynomials in C_D ha...

The Full Systems of Canonical Representatives of Cubic Polynomials with a Given Discriminant

Let us denote C(D) the set of all monic cubic polynomials with integer coefficients having discriminant D. Based on the method presented and computer calculation, I have determined the set C(D) for all $Din mathbb Z$, where $0le D ...

Law of inertia for the factorization of cubic polynomials - the real case

Let D be an integer and let C_D be the set of all monic cubic polynomials x^3 + ax^2 + bx + c with integral coefficients and with the discriminant equal to D. Assume that D<0, D is square-free and 3 does not divide the class numb...

Graphic TSP in cubic graphs

We present a polynomial-time 9/7-approximation algorithm for the graphic TSP for cubic graphs, which improves the previously best approximation factor of 1.3 for 2-connected cubic graphs and drops the requirement of 2-conne...
