Positive Representations of a Class of Complex, Periodic Measures


  • Jacek WOSIEK

Primary authors


A positive representation for a sample of complex densities is constructed. In particular, complex measures on a direct product of $U(1)$ groups are studied. After identifying general conditions which such representations should satisfy, several concrete realisations are proposed. Their performance is illustrated in few concrete examples representing problems in abelian lattice gauge theories.
