Abstract
In this paper, we study the principal functions corresponding to the eigenvalues and the spectral singularities of the boundary value problem (BVP) an-1yn-1 + bnyn + anyn+1 = λyn, n∈ ℕ (γ0 + γ1λ + γ2λ2)y1 + (β0 _ β1λ + β2λ2)yo = 0 where (an) and (bn) n ∈ ℕ are complex sequences, γi βi, ∈ and ℂ is a eigenparameter.
