调和三项式的Egerváry定理

Egerváry's theorems for harmonic trinomials

Gerardo Barrera, Waldemar Barrera, Juan Pablo Navarrete

AI总结:

本文将Egerváry关于三项式根重合的经典定理推广到调和三项式,给出两个调和三项式根集在旋转、反射及其复合下相同的充要条件。

摘要:

在本文中,我们研究了称为调和三项式的缺项调和多项式在复平面中根的排列。我们提供了充分必要条件,使得两个一般调和三项式在复平面中具有相同的根集,最多相差一个绕原点的旋转、关于实轴的反射,或前述两种变换的复合。这将J. Egerváry 1930年关于三项式的结果推广到调和三项式的情形。

英文摘要:

In this manuscript, we study the arrangements of the roots in the complex plane for the lacunary harmonic polynomials called harmonic trinomials. We provide necessary and sufficient conditions so that two general harmonic trinomials have the same set of roots up to a rotation around the origin in the complex plane, a reflection over the real axis, or a composition of the previous both transformations. This extends the results of J. Egerváry 1930 for the setting of trinomials to the setting of harmonic trinomials.
