Large isoperimetric regions in the product of a compact manifold with Euclidean space

Manuel Ritoré, Efstratios Vernadakis

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\…
