✦ Synopsis


We give criteria of pointwise regularity for expansions on Haar or Schauder basis (or spline-type wavelets) corresponding to large Ho lder exponents. As an application, we determine the exact Ho lder regularity of the Polya function at every point and show that it is multifractal.

We advance a reformulation of the Hartree᎐Fock problem in the context of the local-scaling transformation version of density functional theory. Explicit functionals of the energy are obtained. These functionals are expressed in terms of both the one-particle density and the local-scaling transformat
