Nonlinear problems for $\Delta_p$ and $\Delta$
The conference took place 10-14 August 2009 in Linköping.
The aim of the conference was to cover $p$-harmonic functions, $\infty$-harmonic functions, $p$-parabolic functions, water waves and related subjects such as various types of generalizations including quasiminimizers, the porous media equation and the corresponding theories on metric spaces.
A major part of the conference was devoted to four series of three lectures each. These series were given by the following speakers:
Michael Crandall (Santa Barbara):
The $\infty$-Laplacian and
other aspects of $L^\infty$ variational problems
Juha Kinnunen (Helsinki Tech): Superparabolic functions
Olli Martio (Helsinki): Quasiminimizers - definitions, constructions and capacity estimates
John Toland (Bath): Bernoulli free boundaries, Lecture 1, Lecture 2, Lecture 3.
The following invited speakers participated in the conference.
Walter Craig (McMaster, Hamilton): Normal forms for surface water waves
Ugo Gianazza (Pavia): Continuity of the Saturation in the Flow of Two Immiscible Fluids in a Porous Medium
Mark Groves (Saarbrücken): Existence and conditional energetic stability of three-dimensional fully localised solitary gravity-capillary water waves
Robert Jensen (Loyola, Chicago): Curvature flow connections with $\Delta_\infty$
Nikolay Kuznetsov (St Petersburg): The Benjamin-Lighthil conjecture for nearcritical values of Bernoulli's constant
Peter Lindqvist (Trondheim): A minimax problem with variable exponent
Kaj Nyström (Umeå): Regularity and Free Boundary Regularity for the p-Laplace Operator in Reifenberg Flat and Ahlfors Regular Domains
Xiao Zhong (Jyväskylä): Regularity of p-harmonic functions in the Heisenberg group
There were about 20 short communications (25 min) in two parallel sessions.
There was an excursion on Wednesday afternoon and conference dinners on Tuesday and Thursday.

The lecture halls have whiteboards. There will also be computers available for the talks and projectors for slides and computers.The participants will have access to a room with computers, as well as the possibility to connect to the Internet using wireless connections on their own laptops.
