Abstract

We prove Michael-Simon type Sobolev inequalities for nn-dimensional submanifolds in (n+m)(n+m)-dimensional Riemannian manifolds with nonnegative kk-th intermediate Ricci curvature by using the Alexandrov-Bakelman-Pucci method. Here k=min(n1,m1)k=\min(n-1,m-1). These inequalities extends Brendle's Michael-Simon type Sobolev inequalities on Riemannian manifolds with nonnegative sectional curvature (arXiv:2009.13717) and Dong-Lin-Lu's Michael-Simon type Sobolev inequalities on Riemannian manifolds with asymptotically nonnegative sectional curvature (arXiv:2203.14624) to the kk-Ricci curvature setting. In particular, a simple application of these inequalities gives rise to some isoperimetric inequalities for minimal submanifolds in Riemannian manifolds.
