Traces of BMO-Sobolev spaces
Traces of BMO-Sobolev spaces
The trace operator RF(x) = F(x, 0) where F\x, t) is a function of x e R" and / G R1 maps Ia(BMO), the 5MO-Sobolev space of Riesz potentials of order a of functions of bounded mean oscillation on R" + 1, onto the homogeneous Besov space A¡J(oo, oo) on …
