实舒伯特微积分:多项式系统和Shapiro和Shapiro的一个猜想

Real Schubert Calculus: Polynomial systems and a conjecture of Shapiro and Shapiro

Frank Sottile

摘要:

鲍里斯·夏皮罗和迈克尔·夏皮罗有一个关于舒伯特演算和实枚举几何的猜想,它将给出无穷多个实多项式的零维系统族(包括超定组族)--所有的解都是实的。它与线性系理论中的极点配置问题和全正矩阵有关。我们给令人信服的计算证据,其有效性,证明它的无穷多个家庭的枚举问题,显示如何一个简单的版本意味着更一般的版本,并提出一个反例的一般版本的猜想。

英文摘要:

Boris Shapiro and Michael Shapiro have a conjecture concerning the Schubert calculus and real enumerative geometry and which would give infinitely many families of zero-dimensional systems of real polynomials (including families of overdetermined systems)--all of whose solutions are real. It has connections to the pole placement problem in linear systems theory and to totally positive matrices. We give compelling computational evidence for its validity, prove it for infinitely many families of enumerative problems, show how a simple version implies more general versions, and present a counterexample to a general version of their conjecture.
