Abstract
In this work we study the following third order differential equation:
Ly := y + (q(x, y) + λ)y = f ∈ L2(R), R = (–∞,∞),λ > 0, where q(x, y) ≥ 1 is a continuous function in all its variables. We will deal with the following questions:
(a) The existence of a solution to equation (1) in the space L2(R) where L2(R) is the
space of square summable functions.
(b) Additional conditions on the third derivative of this solution to belong to the
space L2(R)
