Geometry of currents, intersection theory and dynamics of horizontal-like maps
We introduce a geometry on the cone of positive closed currents of bidegree
(p,p) and apply it to define the intersection of such currents. We also
construct and study the Green currents and the equilibrium measure for
horizontal-like mappings. The Green currents satisfy some extremality
properties. The equilibrium measure is invariant, mixing and has maximal
entropy. It is equal to the intersection of the Green currents associated to
the horizontal-like map and to its inverse.Comment: 32 pages, to appear in Ann. Inst. Fourie
On the compactification of hyperconcave ends and the theorems of Siu-Yau and Nadel
We show that the pseudoconcave holes of some naturally arising class of
manifolds, called hyperconcave ends, can be filled in, including the case of
complex dimension 2 . As a consequence we obtain a stronger version of the
compactification theorem of Siu-Yau and extend Nadel's theorems to dimension 2.Comment: 13 pages, AMSLaTeX, short version accepted for publication in
