We study a convergence result of Bourgain–Brezis–Mironescu (BBM) using Triebel-Lizorkin spaces. It is well known that as spaces, and. When, thenorm becomes thenorm but BBM showed that thenorm becomes thenorm. Naively, forthis seems like a contradiction, but we resolve this by providing embeddings ofintoforwith sharp constants with respect to. As a consequence we obtain an-version of the BBM-result, and obtain several more embedding and convergence theorems of BBM-type that to the best of our knowledge are unknown.
