Spectral properties of some regular boundary value problems for fourth order differential operators

In this paper we consider the problem where λ is a spectral parameter; p j ( x ) ∈ L 1 (0, 1), j = 0, 1, 2, are complex-valued functions; α s;l , s = 1, 2, 3, , are arbitrary complex constants; and σ = 0, 1. The boundary conditions of this problem are regular, but not strongly regular. Asymptotic fo...
