In this paper we construct families of algebraic nonsingular 3- folds X of general type having minimal $K_X^3$ for their $p_g$, in order that the canonical morphism is finite of degree 3. For such 3-folds it is $K_X^3=3(p_g-3)$ and $p_g$ is odd.

Abstract
In this paper we construct families of algebraic nonsingular 3- folds X of general type having minimal $K_X^3$ for their $p_g$, in order that the canonical morphism is finite of degree 3. For such 3-folds it is $K_X^3=3(p_g-3)$ and $p_g$ is odd.File in questo prodotto:
