Abstract:

In this paper we study the following problem: Given that certain functionals of $u$ and its derivatives belong to given L-classes over the infinite interval, what can be said about the L-classes of other functionals? Utilizing a simple device from the theory of linear differential equations, we obtain a number of results due to Landau, Kolmogoroff, Halperin-von Neumann, and Nagy, together with some extensions.
