摘要:

It is shown that an arbitrary function from D ( Rn to Rm will become C0,α -continuous in almost every xD after restriction to a certain subset with limit point x. For nm differentiability can be obtained. Examples show the H¨older exponentn α = min{1, n/m} is optimal.

关键词: H¨older continuity, Lipschitz continuity, differentiability, restriction, weak solution
