Abstract: Assume that Ω is a bounded strictly pseudoconvex domain with C2 boundary. We prove the existence of a nonconstant inner function on Ω with gradient in L1(Ω). read more here.

Abstract: Wannier functions that are maximally localized help in understanding many properties of crystalline materials. In the absence of topological obstructions, they are at least exponentially localized. In some cases such as flat-band Hamiltonians, it is… read more here.
