由推广的Sturm-Liouville定理生成的有限型不完全对称正交多项式

Incomplete Symmetric Orthogonal Polynomials of Finite Type Generated by a Generalized Sturm-Liouville Theorem

Mohammad Masjed-Jamei, Zahra Moalemi, Nasser Saad

摘要:

在经典情况下,正交多项式序列的方式使得第$ n $个多项式具有精确的次数$n$。这样的序列是完备的,并且形成任意多项式的空间的基。本文引入了一些不包含所有次数的有限正交多项式的不完备集,但它们是某些对称广义Sturm-Liouville问题的解。虽然这样的多项式不具备所有的性质,在经典的情况下,他们可以应用于函数逼近理论,因为我们将计算其显式的范数平方值。

英文摘要:

In a classical case, orthogonal polynomial sequences are in such a way that the $ n $th polynomial has the exact degree $n$. Such sequences are complete and form a basis of the space for any arbitrary polynomial. In this paper, we introduce some incomplete sets of finite orthogonal polynomials that do not contain all degrees but they are solutions of some symmetric generalized Sturm-Liouville problems. Although such polynomials do not possess all properties as in classical cases, they can be applied to functions approximation theory as we will compute their explicit norm square values.
