Abstract
Let \(\mathcal X\) be a non-degenerate projective algebraic curve and denote by \(\mathcal X^{'}\) its strict dual curve. The map \(\gamma :\mathcal X\longrightarrow \mathcal X^{'}\) is called (strict) Gauss map of \(\mathcal X\). In this manuscript, we study the separable degree of the Gauss map of curves defined over finite fields. In particular, we give a generalization of a known result on the separable degree of the Gauss map of plane Frobenius nonclassical curves. We also obtain a characterization of certain plane strange curves.
