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.

Starting from fall 2017, we have a new concept for the joint seminar. The seminar is held once in 3 weeks but with two one-hour talks. The time is the same as before Fridays at 14-16. The place alternates between the University of Helsinki Kumpula Campus (Exactum room C124) and the Aalto University Otaniemi Campus (Main Building room M3).

The schedule for the fall 2017:

  • 29.9. (Kumpula)
  • 20.10. (Otaniemi)
  • 10.11. (Kumpula)
  • 1.12. (Otaniemi)

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:


  • 21.2. 12:15  Jung-Tae Park (Seoul National University): Global gradient estimates for measure data problems in nonsmooth domains – M3 (M234)
  • 23.2. 14:15  Pekka Lehtelä (Aalto): Obstacle problem for the porous medium equation – Kumpula Exactum C124
  • 23.2. 15:15  Nick Lindemulder (TU Delft): A randomized difference norm for vector-valued Bessel potential spaces – Kumpula Exactum C124

    In this talk we discuss a randomized difference norm characterization for Bessel potential spaces in the UMD Banach space-valued setting. The main ingredients are R-boundedness results for Fourier multiplier operators, which are of independent interest. As an application we characterize the pointwise multiplier property of the indicator function of the half-space on these spaces. All results are proved in the setting of weighted spaces

  • 28.2. 12:15  Pekka Alestalo (Aalto University): Extension of bilipschitz maps: A survey – M3 (M234)
  • 7.3. 12:15  Sebastian Schwarzacher (University of Bonn): TBA – M3 (M234)
  • 14.3. 12:15  Ilmari Kangasniemi (University of Helsinki): TBA – M3 (M234)
  • 21.3. 12:15  Sylvester Eriksson-Bique (UCLA): TBA – M3 (M234)
  • 23.3. 14:15  TBA: TBA – M3 (M234)
  • 23.3. 15:15  Antti Vähäkangas (Jyväskylä): TBA – M3 (M234)
  • 28.3. 12:15  Augusto Gerolin (University of Jyväskylä): Optimal Transport meets Density Functional Theory – M3 (M234)
  • 11.4. 12:15  Amal Attouchi (University of Jyväskylä): Qualitative properties of viscosity solutions of a degenerate or singular parabolic equation in non-divergence form. – M3 (M234)
