| dc.description | In this paper, we introduce a concept of B-minimal sub-manifolds and discuss the stability of such a sub-manifold in a Riemannian manifold $(M,g)$. Assume $B(x)$ is a smooth function on $M$. By definition, we call a sub-manifold $Σ$ {\em B-minimal} in $(M,g)$ if the product sub-manifold $Σ\times S^1$ is a {\em minimal} sub-manifold in a warped product Riemannian manifold $(M\times S^1, g+e^{2B(x)}dt^2)$, so its stability is closely related to the stability of solitons of mean curvature flows as noted earlier by G. Huisken, S. Angenent, and K. Smoczyk. We can show that the "grim reaper" in the curve-shortening problem is stable in the sense of "symmetric stable" defined by K. Smoczyk. We also discuss the graphic B-minimal sub-manifold in $R^{n+k}$. | |
