Abstract
In the present paper, we consider a new boundaries conditions of the third
kind. we prove the completeness, the basis property, and the minimality of the eigenfunctions in the space W2 pl(0; π), where W2 pl(0; π) be the set of functions f 2 (Wp2l(0; π)),
satisfying of the following conditions: f(2k−1)(0) = 0; k = 1; 2; :::; l.
