Large isoperimetric regions in the product of a compact manifold with Euclidean space
Manuel Ritoré Cortés Universidad de Granada
Given a compact Riemannian manifold $M$ without boundary, we show that large isoperimetric regions in $M\times\mathbb{R}^k$ are tubular neighborhoods of $M\times\{x\}$, with $x\in \mathbb{R}^k$.
