Colloquium de l'IDPNonlinear Fourier transform and the Beltrami equation
Kari ASTALA (Helsinki)
Thursday 15 January 2009 14:00 - Orléans - Amphithéâtre S
Beltrami equation has its roots in complex analysis and quasiconformal geometry, but its role in elliptic PDE's has grown equally important. In this talk we give an overview of recent connections to mathematical applications and impedance tomography, through the nonlinear Fourier transform associated with the Beltrami equation.
