In this article we consider surfaces in the product space $\mathbb{H}^2 \times \mathbb{R}$ of the hyperbolic plane $\mathbb{H}^2$ with the real line. The main results are: a description of some geometric properties of minimal graphs; new examples of complete minimal graphs; the local classification of totally umbilical surfaces.
-In questo lavoro si considerano le superfici nel prodotto $\mathbb{H}^2 \times \mathbb{R}$ del piano iperbolico con la retta reale. I risultati principali sono: la descrizione geometrica di alcune proprietà dei grafici minimi; la determinazione di nuovi esempi di grafici minimi completi; la classificazione locale delle superfici totalmente ombelicali.
