We describe a graph parametrization of rational quadratic differentials with presence of a simple pole, whose critical trajectories form a network depending on parameters focusing on the network topological jumps. Obtained bifurcation diagrams are associated with the Stasheff polytopes.

Combinatorial analysis of the period mapping: the topology of 2D fibres

We study the period mapping from the moduli space of real hyperelliptic curves to a Euclidean space. The mapping arises in the analysis of Chebyshev’s construction used in the constrained

Quadratic Differentials and Weighted Graphs on Compact Surfaces

We prove that for every simply connected graph Γ embedded in a compact surface R of genus g≥o, whose edges e i kj carry positive weights w i kj , there exist a complex structure on R and a

Combinatorial description of a moduli space of curves and of extremal polynomials

For the description of extremal polynomials (that is, the typical solutions of least deviation problems) one uses real hyperelliptic curves. A partitioning of the moduli space of such curves into

Motivic Donaldson-Thomas invariants: Summary of results

This is a short summary of main results of our paper arXiv:0811.2435 where the concept of motivic Donaldson-Thomas invariant was introduced. It also contains a discussion of some open questions from

Critical Measures, Quadratic Differentials, and Weak Limits of Zeros of Stieltjes Polynomials

We investigate the asymptotic zero distribution of Heine-Stieltjes polynomials – polynomial solutions of second order differential equations with complex polynomial coefficients. In the case when all

EQUILIBRIUM DISTRIBUTIONS AND DEGREE OF RATIONAL APPROXIMATION OF ANALYTIC FUNCTIONS

A theorem is proved on the degree of rational approximation of sequences of analytic functions given by Cauchy-type integrals of the form The theorem is formulated in terms connected with the

Extremal domains associated with an analytic function I

In this paper we investigate the following two extremal problems: A) Let F be a continuum in the extended complex plane that does not divide and let f(z) be a function analytic on F By D we denote

Classification of Complete N = 2 Supersymmetric Theories in 4 Dimensions

We define the notion of a complete N = 2 supersymmetric theory in 4 dimensions as a UV complete theory for which all the BPS central charges can be arbitrarily varied as we vary its Coulomb branch
