Conference on Harmonic Analysis, Geometric Measure Theory and Quasiconformal Mappings



The purpose of the conference is to provide researchers working in harmonic analysis, quasiconformal mappings or geometric measure theory with a scientific event designed to promote a deep interaction between the three subjects. When the theory of quasiconformal mappings reached some maturity its strong relation to real analysis (in particular to Calderón-Zygmund theory, through its connection with the Beurling transform) became apparent. In the past two decades one has realised that this relation is even more intimate than it was expected, through the work on area distortion, connection with PDEs etc. In particular, area distortion is related to the precise value of the norm of the Beurling transform as an operator on Lp, and this has lead to connections with probability theory (martingales) and control theory (the Bellman function). On the other hand, the mapping properties of Calderón-Zygmund operators of last generation, in which the underlying measure is a rather general measure on Euclidean space, has shown to be intimately connected to rectifiability (uniform rectifiability) and thus to geometric measure theory. Recently a new connection between geometric measure theory and quasiconformal mappings has also emerged, when studying removability problems for quasiregular functions.
The main goal of the conference is to bring together the leading worldwide experts in each of the subjects listed above and young researchers, including postdocs and advanced doctoral students working in related topics. One expects that new perspectives will arise, new problems will be raised and new light will be shed on old open problems.
