Teichmüller’s problem from 1944 is this: Given x ∈ [0, 1) find and describe the extremal quasiconformal map f : D → D, f |∂D = identity and f(0) = −x ≤ 0. We consider this problem in the setting of minimisers of Lp-mean distortion. The classical result is that there is an extremal map of Teichmüller type with associated holomorphic quadratic differential having a pole of order one at x, if x 6= 0. For the Lp-norm, when p = 1 it is known that there can be no locally quasiconformal minimiser… Expand

THE TEICHMÜLLER PROBLEM FOR MEAN DISTORTION
The classical Teichmuller problem asks one to identify the deformation of a disk which holds the boundary fixed, moves the origin to a given point and which minimises the maxi- mal conformalExpand
Extremal mappings of finite distortion
The theory of mappings of finite distortion has arisen out of a need to extend the ideas and applications of the classical theory of quasiconformal mappings to the degenerate elliptic setting whereExpand
The $L^p$ Teichm\"uller theory: Existence and regularity of critical points
We study minimisers of the $p$-conformal energy functionals, \[ \mathsf{E}_p(f):=\int_\ID \IK^p(z,f)\,dz,\quad f|_\IS=f_0|_\IS, \] defined for self mappings $f:\ID\to\ID$ with finite distortion andExpand
Extremal mappings of finite distortion and the Radon-Riesz property
We consider Sobolev mappings f ∈ W (Ω,C), 1 < q < ∞, between planar domains Ω ⊂ C. We analyse the Radon-Riesz property for convex functionals of the form f 7→ ∫ Ω Φ(|Df(z)|, J(z, f)) dz and show thatExpand
Non-variational extrema of exponential Teichmüller spaces
The exponential Teichmuller spaces $E_p$, $0\leq p \leq \infty$, interpolate between the classical Teichmuller space ($p=\infty$) and the space of harmonic diffeomorphisms $(p=0)$. In this article weExpand

Quasiregular Families Bounded in $$L^p$$ and Elliptic Estimates
We prove that a family of quasiregular mappings of a domain $\Omega$ which are uniformly bounded in $L^p$ for some $p>0$ form a normal family. From this we show how an elliptic estimate on aExpand
