“…For a glimpse of long time existence and asymptotic analysis results for smooth IMCF in various ambient manifolds see [1,3,12,15,16,29,30,31,33]. For our purposes here the results of Scheuer [29,30] and the author [3] are particularly significant. In [29,30] Scheuer gives long time existence and asymptotic analysis results for rotationally symmetric metrics with nonpositive radial curvature and later generalizing to warped products.…”
