Sunto
Si studiano le applicazioni $p$-tangenti da $\mathbb{R}^{m}$ a $\mathbb{S}^{n}$ date come estensioni omogenee di $k$-forme armoniche. Vengono ricavate condizioni necessarie sul grado $k$ affinche tali applicazioni $p$-tangenti siano di energia minima. Una classificazione completa viene data nel caso in cui tali applicazioni tangenti di energia minima vadano da $\mathbb{R}^{8}$ su $\mathbb{S}^{4}$.
