On traces of anisotropic Triebel-Lizorkin spaces

In collaboration with W. Sickel (Germany) a project is begun on the traces of Triebel--Lizorkin spaces with anisotropies in both the smoothness index and the integral exponents. Preliminary investigations show that the trace space as a novelty will be another Triebel--Lizorkin space (instead of the usual Besov space known from the isotropic case).
