Lipschitz constant

The smallest such value of q is sometimes called the Lipschitz constant.

Any such q is a Lipschitz constant. There isn't the Lipschitz constant. 84.191.234.177 (talk) 20:09, 26 June 2008 (UTC)[reply]

Contractive Mapping Theorem

Maybe a little note about Edelstein's contractive mapping theorem, a generalized version of the Contraction mapping theorem, which sets Lipschitz constant to be equal to 1 but makes the inequality strict should be added? 202.36.179.66 (talk) 02:06, 24 September 2008 (UTC)R[reply]

With what additional condition? Compactness? Algebraist 12:49, 24 September 2008 (UTC)[reply]
