Analysis and PDE seminars at Aalto

Harmonic analysis and PDE seminar

As of January 2016, we are launching a joint seminar of the Harmonic Analysis group at the University of Helsinki, and the Nonlinear PDE group at the Aalto University.

The seminar is held on Fridays at 14-16, and the place alternates between the University of Helsinki Kumpula Campus (Exactum room C123) and the Aalto University Otaniemi Campus (Main Building room M3).

In January and February 2017, we we will have a break in the joint seminar, but the seminar will continue at the same time (Friday 14-16) at Aalto. Later in the spring, we will think about a new concept for the joint seminar. We might have a joint seminar approximately every second week with two shorter talks.

Everyone interested is welcome!

Organizers of the seminar:

See the webpage of the seminar. The talks are listed in the end of this page as well.

Analysis and geometry seminar

Analysis and geometry seminar is held usually on Wednesdays at 12-14 in M3.

Organizers of the seminar:


  • 22.2. 12:15  Aleksis Koski (University of Jyväskylä): Nonlinear Beltrami equations: Improved regularity – M3 (M234)

    The Beltrami equation is a planar elliptic equation generalizing the Cauchy-Riemann equations for holomorphic functions. In this talk we will introduce this equation along with its linear and nonlinear variants. We will explain some recent results on the nonlinear Beltrami equation related to the regularity of solutions, uniqueness properties of normalized solutions and the positivity of the Jacobian. We also study connections to divergence-type equations. The talk is based on joint work with Kari Astala, Albert Clop, Daniel Faraco and Jarmo Jääskeläinen.
