Convergence problems of the eigenfunction expansions for polyharmonic operators
This research focuses on convergence and summability problems of the eigenfunctions expansions of differential operators related to polyharmonic operator in closed domain. The polyharmonic operator (-- ∆)‴,m ∈ Z+ is the elliptic operator of order 2m with domain consists of classes of infinitely diff...
