Quasiconformal mappings, from Ptolemy's geography to the work of Teichmüller
, 2018 The origin of quasiconformal mappings, like that of conformal mappings, can be traced back to old cartography where the basic problem was the search for mappings from the sphere onto the plane with minimal deviation from conformality, subject to certain ...

Numerical Methods for Non-divergence Form Second Order Linear Elliptic Partial Differential Equations and Discontinuous Ritz Methods for Problems from the Calculus of Variations [PDF]
, 2017 This dissertation consists of three integral parts. Part one studies discontinuous Galerkin approximations of a class of non-divergence form second order linear elliptic PDEs whose coefficients are only continuous.

Geometry on surfaces, a source for mathematical developments
We present a variety of geometrical and combinatorial tools that are used in the study of geometric structures on surfaces: volume, contact, symplectic, complex and almost complex structures.

Absence of Lavrentiev Phenomenon for Functionals with (p,q)-growth [PDF]
The aim of this thesis is to provide the absence of Lavrentiev phenomenon for integral functionals of the following type • F(u) = \int_Ω f(x,Du(x)) dx, where Ω is a subset of Rn and x → ∂f/∂z is α-Hölder continuous, we denote f=f(x,z ...
