We give a survey of our previous work on relatively minimal isotrivial fibrations \(\alpha :X \longrightarrow C\), where \(X\) is a smooth, projective surface and \(C\) is a curve. In particular, we consider two inequalities involving the numerical invariants \(K_X^2\) and \(\chi (\mathcal {O}_X)\) and we illustrate them by means of several examples and counter examples.
