We characterized the distances from Bloch functions to some Möbius invariant spaces by high order derivatives. Moreover, the boundedness and compactness of the products of composition and di ...

Let u be a harmonic function in the upper half space $\mathbb{R}^{n+1}_+$ and A(u) its (truncated) area function. Classical results of Calderón, Stein and Zygmund assert that the following two sets {x ...

Our goal is to provide, within a mean-field approximation, a general formula for the superfluid weight of a multiband system that can include topologically nontrivial bands and/or flat bands. A finite ...
