Hermitian-holomorphic Deligne cohomology, Deligne pairing for singular metrics, and hyperbolic metrics
Ettore Aldrovandi
We introduce a model for Hermitian holormorphic Deligne cohomology on a projective algebraic manifold which allows to incorporate singular hermitian structures along a normal cross…
Hermitian-holomorphic (2)-Gerbes and tame symbols
Ettore Aldrovandi
We observe that the line bundle associated to the tame symbol of two invertible holomorphic functions also carries a fairly canonical hermitian metric, hence it represents a class…
Homological algebra of multivalued action functionals
E. Aldrovandi
We outline a cohomological treatment for multivalued (classical) action functionals. We point out that an application of Takens' theorem, after Zuckerman, Deligne and Freed, allows…
Toda Field Theory as a Clue to the Geometry of --Gravity
Ettore Aldrovandi, Gregorio Falqui
We discuss geometrical aspects of Toda Fields generalizing the links between Liouville gravity and uniformization of Riemann surfaces of genus greater than one. The framework is th…
