On the Riesz basis property of the root functions in certain regular boundary value problems
N. B. Kerimov, Kh. R. Mamedov M. V. Lomonosov Moscow State University
Abstract:
The differential operator $ly=y''+q(x)y$ with periodic (antiperiodic) boundary conditions that are not strongly regular is studied. It is assumed that $q(x)$ is a complex-valued function of class $C^{(4)}[0,1]$ and $q(0)\ne q(1)$. We prove that the system of root functions of this operator forms a Riesz basis in the space $L_2(0,1)$.
