| contents | The aim of this paper is to study the problem of existence of remotely almost periodic solutions for the scalar differential equation $x'=f(t,x),$ where $f:\mathbb R\times \mathbb R\to \mathbb R$ is a continuous, monotone in $x$ and remotely almost periodic in $t$ function. We prove that every solution $φ$ of this equation bounded on the semi-axis $\mathbb R_{+}$ is remotely almost periodic. This statement is a generalization of the well-known Opial's theorem for remotely almost periodic scalar differential equations. We also establish a similar statement for scalar difference equations. |
