Abstract

We consider a boundary value problem

where f ∈ L~p~ (ℝ), p ∈ [1, ∞] (L∞ (ℝ) ≔ C (ℝ)) and 0 ≀ q ∈ L^loc^~1~ (ℝ). For a given p ∈ [1, ∞], for a correctly solvable problem (0.1) in L~p~ (ℝ), we obtain minimal requirements to a positive, continuous function Θ(x) for x ∈ ℝ under which, regardless of f ∈ L~p~ (ℝ), the solution y ∈ L~p~ (ℝ) of problem (0.1) satisfies the equality
