Asymptotic and exterior Dirichlet problems for the minimal surface equation in the Heisenberg group with a balanced metric

Fidelis Bittencourt, Edson S. Figueiredo, Pedro Fusieger +1

It is proved that the Heisenberg group $Nil_{3}$ with a balanced metric, the sum of the left and right invariant metrics, splits as a Riemannian product $\…

Minimal isoparametric submanifolds of $S^{7}$ and octonionic eigenmaps

Fidelis Bittencourt, Daniel Bustos, Edson Figueiredo +2

We use the octonionic multiplication $\cdot$ of $S^{7}$ to associate, to each unit normal section $η$ of a submanifold $M$ of $S^{7},$ an octonionic Gauss map $γ_…
