Abstract

We investigate how the behaviour, especially at  ±infty,  of continuous real solutions  f(t)  to the equation  f(t) = a₁ f(t+h₁) + a₂ f(t-h₂),  where  a₁, a₂, h₁, h₂  are positive real constants, depends on the values of these parameters. Definitive answers are given, except in certain cases when  h₁/h₂  is rational.
