Abstract

In the late 80s, V. Arnold and V. Vassiliev initiated the study of the topology of the space of real univariate polynomials of a given degree d and with no real roots of multiplicity exceeding a given positive integer. Expanding their studies, we consider the spaces \(P^{c\Theta}\)of real monic univariate polynomials of degree \(d\) whose real divisors avoid d sequences of root multiplicities taken from a given poset \(\Theta\) of compositions, closed under certain natural combinatorial operations.
