## Traces of Besov and Triebel-Lizorkin spaces on domains We determine the trace of Besov spaces B s p,q (Ω) and Triebel-Lizorkin spaces F s p,q (Ω), characterized via atomic decompositions, on the boundary of C k domains Ω for parameters 0 < p, q ≤ ∞ and s > 1 p . The limiting case s = 1 p is inv

The Bethe strip of width m is the cartesian product B × {1, . . . , m}, where B is the Bethe lattice (Cayley tree). We prove that Anderson models on the Bethe strip have "extended states" for small disorder. More precisely, we consider Anderson-like Hamiltonians H λ = 1 2 Δ ⊗ 1 + 1 ⊗ A + λV on a Bet
