Abstract AR
هدف هذا البحث برهنة نظرية حول متوسطات ريس للتوسيعات بالنسبة إلى قواعد ريس التي توسع النتائج السابقة ل (لوي و طاهر) المتحققة على مؤثر شرودنكر و المؤثر التفاضلي الاعتيادي من الرتبة الرابعة إلى مؤثر تفاضلي من الرتبة 2m باستخدام الدوال الذاتية للمؤثر التفاضلي الاعتيادي.
Abstract EN
The aim of this paper is to prove a theorem on the Riesz means of expansions with respect to Riesz bases, which extends the previous results of [1] and [2] on the Schrödinger operator and the ordinary differential operator of 4-th order to the operator of order 2m by using the eigen functions of the ordinary differential operator.
Some Symbols that used in the paper : || || the uniform norm.
<, > the inner product in L2.
∂G the set of all boundary elements of G.
û the dual function of u.
