Project Title: Modern analysis and Geometry

This proposal sits at the forefront of two central areas of modern mathematics; nonlinear analysis and low dimensional topology & geometry; unified by themes in conformal geometry and geometric function theory. We attack important longstanding problems with wide ranging applications. These include the classification of conformal dynamical systems on manifolds and their dynamically defined invariants. This project interacts with our novel results in geometric group theory. We investigate the structure and classification of arithmetic hyperbolic orbifolds extending our solution of Sigel's1945 problem by developing new methods to attack key problems in hyperbolic geometry.

Project Title: Advances in scattering theory and solvable models

Contact with the external world takes place by detecting waves and particles scattered by objects in it; understanding this process is one of the most important tasks of physical and mathematical models. Classical schemes fail for operators with continuous spectrum (divergence of perturbation series). Typical problems include 1. Scattering of acoustic waves - Helmholtz resonator; 2. Scattering of electrons in quantum networks; 3. Plasma waves in electron channels: propagation and trapped modes. We develop innovative methods to solve these problems via fitting zero-range solvable models, intermediate operators, and nonlinear resonance duality. Applications in quantum networks and tomography are developed.

Project Title: Modern Analysis and Geometry

This research investigates two central areas of modern mathematics; nonlinear analysis and low dimensional topology linked by conformal geometry. These areas have undergone enormous growth due to a new understanding of their relevance and far reaching applications, and our research is helping to understand important and longstanding questions in these areas.
