分段多项式函数零点数量的上界
An upper bound on the number of zeros of a piecewise polinomial function
AI总结:
本文建立了单变量样条函数的节点与零点分布之间的精确关系,并应用于证明De Concini和Procesi猜想在单变量单模情况下的正确性,同时通过反例表明去掉单模假设后猜想不成立。
摘要:
本文建立了单变量样条函数的节点与其零点丰度和分布之间的精确联系。作为应用,证明了De Concini和Procesi提出的一个猜想在特殊的单变量单模情况下成立。作为补充,通过计算一个反例表明,当去掉单模假设时,同一猜想不成立。
英文摘要:
A precise tie between a univariate spline's knots and its zeros abundance and dissemination is formulated. As an application, a conjecture formulated by De Concini and Procesi is shown to be true in the special univariate, unimodular case. As a supplement, the same conjecture is shown, through computing a counterexample, to be false when unimodularity hypothesis is dropped.
