Taut submanifold

From Wikipedia, the free encyclopedia

In mathematics, a (compact) taut submanifold N of a space form M is a compact submanifold with the property that for every the distance function

is a perfect Morse function.[citation needed]

If N is not compact, one needs to consider the restriction of the to any of their sublevel sets.
