ABSTRACT
This paper deals with approximation numbers of the compact trace operator of an anisotropic Besov space into some -space,
where is an anisotropic -set, . We also prove homogeneity estimates, a homogeneous equivalent norm and the localization property in .
Key words: anisotropic function spaces, fractals, approximation numbers, traces.
