P_(n+1) (x)=(x-c_(n+1) ) P_n (x)-d_(n+1) (x^2+1) P_(n-1) (x), n≥1,

with P_0 (x)=1 and P_1 (x)=x-c_1, where 〖{c_n}〗_(n≥1) is a real sequence and 〖{d_(n+1)}〗_(n≥1) is a positive chain sequence. The zeros of the polynomials P_n are simple and lie on the real line. It turns out that the polynomial P_n, for any n≥2, is the characteristic polynomial of a simple n×n generalized eigenvalue problem. It is also shown that with this R_II type recurrence relation one can always associate a positive measure on the unit circle. The orthogonality property satisfied by P_n with respect to this measure is also found.

We extend some equilibrium-type results first conjectured by Ambrus, Ball and Erdélyi and then proved recently by Hardin, Kendall and Saff. Similarly to them, we too work on the torus T"?" ["0,2π" ) (unit circle), but a motivation comes from an analogous setup on the unit interval, investigated earlier by Fenton.

The problem is to minimize (with respect to the arbitrary translates y_0=0,y_j∈T , j=1,…,n) the maximum of the sum function F(?)?K_0 (?)+∑_(j=1)^n?〖K_j (?-y_j 〗), where K_j`s are certain fixed ``kernel functions``. If they are concave on T, except for having possible singularities or cusps at zero, then the translates by y_j will have singularities at y_j (while in between these nodes the sum function F still behaves regularly). So one can consider the maxima m_i on each subinterval between the nodes y_j, and look for the minimization of maxF=max┬i?〖m_i 〗. Also the dual question of maximization of min┬i?〖m_i 〗 arises.

Hardin, Kendall and Saff considered one single, even kernel, K_j=K for j=1,…,n, and Fenton considered the case of the interval [-1,1] with two fixed kernels K_0=J and K_j=K for j=1,…,n. Here we build up a systematic treatment of the situation when all the kernel functions can be different without assuming them to be even.

Finally we discuss a result of Bojanov on algebraic polynomials with prescribed zero order having minimal sup-norm on interval. As an application of our general framework we show a generalization of Bojanov`s result for generalized algebraic polynomials (GAP) and generalized trigonometric polynomials (GTP) as well.

D-stability concept arises is such different areas of mathematics, such as control theory where that kind of problems corresponds to construction of a dynamical system with some special properties of its behaviour, singularity theory and topology, where these problems constituted an important natural example of singularities given by the symmetric group action, metric complex analysis, where those space become an important testing ground for different convexity-type definitions, statistical physics, where different types of stabilities arise in a context of so called theorems of Yang-Lee type.

We study the spaces of polynomials stratified into the sets of polynomial with fixed number of roots inside certain semialgebraic region $\Omega,$ on its border, and at the complement to its closure. Presented approach is a generalization, unification and development of several classical approaches to the stability problems: rootclustering (D-stability) developed by R.E. Kalman, B.R. Barmish, S. Gutman et al., D-decomposition (Yu.I. Neimark,B.T. Polyak, E.N. Gryazina) and universal parameter space method (A. Fam, J. Meditch, J.Ackermann).

Our approach is based on the interpretation of correspondence between roots and coefficients of a polynomial as asymmetric product morphism and applications of methods of real algebraic geometry and topological theory of symmetric products. We study topology of strata and adjacencies between them.

Moreover, we provide an explanation for the special position of classical stability problems: Hurwitz stability, Schur stability, hyperbolicity.
