The goal of the team brought together in this project is to bundle our expertise with the aim of making important contributions to a number of fundamental problems and conjectures in Quantization, Holomorphic Dynamics and Foliation Theory. We will exhibit and exploit the deep ties between these areas and bring them to bear on diverse open questions. Our goal is to provide fresh perspectives and novel problem-solving strategies to encompass these fields and in the long-term to foster in the wider research community a stronger unification of these parts of mathematics.Using as a cornerstone the development of the theory of currents in the complex setting and of the Bergman/Szegö kernel (including L^2 methods) and their systematic exploitation in the study of a number of topics, we address the following interrelated questions: commutation of quantization and reduction on Kähler spaces and Cauchy-Riemann manifolds; hamiltonian actions; quantization of the space of Kähler potentials and of adapted complex structures; Bergman kernel asymptotics, analytic torsion, Newlander-Nirenberg theorem on complex spaces; singularities and accumulation points of a leaf of a holomorphic foliation, especially with non-hyperbolic singularities; unique ergodicity for singular holomorphic foliations; quantitative counting of dynamical phenomena for holomorphic dynamical systems, both in the phase and parameter spaces; equidistribution of zeros of random holomorphic sections.
