AI 中文摘要

本文研究与等差数列指标集相关的广义Wronskian-Hermite(WH)多项式,验证了这类多项式的三个子类的所有非零根均为单根的猜想,这三个子类在自然意义下覆盖了相关参数范围的一半以上;还通过杨图解释了z=0处的根重数,证明部分广义WH多项式可给出Noumi-Yamada系统(一类高阶Painlevé方程)有理解的表示;最后将所得结果应用于多分量Hirota方程的怪波模式大参数渐近分析。

英文摘要

In this paper, we study generalized Wronskian-Hermite (WH) polynomials associated with arithmetic-progression index sets. We verify the conjecture that all nonzero roots are simple for three subclasses of these polynomials, which, in a natural sense, cover more than half of the relevant parameter range. We also provide an interpretation of the root multiplicity at $z=0$ in terms of Young diagrams. In addition, we show that certain members of generalized WH polynomials provide representations of rational solutions of the Noumi-Yamada systems, a family of higher-order Painlevé equations. Finally, we apply our results to the large-parameter asymptotic analysis of rogue wave patterns for the multi-component Hirota equation.
