Abstract
The weak solutions of the p-harmonic equation are, by definition, members of the Sobolev space \(W^{1,p}_{\text {loc}}(\Omega )\). In fact, they are also of class \(C_{\text {loc}}^\alpha (\Omega )\). More precisely, a weak solution can be redefined in a set of Lebesgue measure zero, so that the new function is locally Hölder continuous with exponent \(\alpha =\alpha (n, p)\).
