乘法算子与例外雅可比多项式

Multiplication operator and exceptional Jacobi polynomials

Á. P. Horváth

摘要:

下面研究了Christoffel函数关于例外雅可比多项式的归一化加权倒数。证明了它趋于弱星意义下正交区间的平衡测度。本研究的主要工具是乘法算子和检查相应的平均特征多项式的零点的行为。最后,作为乘法算子的一个应用,研究了某些自反演多项式零点的定位问题。

英文摘要:

Below the normalized weighted reciprocal of the Christoffel function with respect to exceptional Jacobi polynomials is investigated. It is proved that it tends to the equilibrium measure of the interval of orthogonality in weak-star sense. The main tool of this study is the multiplication operator and examination of behavior of zeros of the corresponding average characteristic polynomial. Finally, as an application of multiplication operator, location of zeros of certain self-inversive polynomials are examined.
