Elliptic Partial Differential Equations and Quasiconformal Mappings in the Plane
The book explains that the existence, regularity, and singular set structures for second-order divergence-type equations—the most important class of PDEs in applications—are determined by the mathematics underpinning the geometry, structure, and dimension of fractal sets; moduli spaces of Riemann surfaces; and conformal dynamical systems. These topics are inextricably linked by the theory of quasiconformal mappings. Further, the interplay between them allows the authors to extend classical results to more general settings for wider applicability, providing new and often optimal answers to questions of existence, regularity, and geometric properties of solutions to nonlinear systems in both elliptic and degenerate elliptic settings.
