Abstract

If f is a function of class Lp on the torus and if the subset E of is the peak set of a function of class Ap (UN ), then there is a function g in A p − l, α (UN for all α between zero and one with g = f on E. The peak sets of functions of class Ap (Un ) lie in locally closed interpolation submanifolds of the torus of class Lp . but an example shows that they need not lie in closed interpolation submanifolds.
