We provide several estimates which involve the distance to L∞ in some function spaces, the composition operator induced by a quasiconformal mapping and the logarithm of the Jacobian of a quasiconformal mapping. Our results are sharp in the two dimensional case.

### Quasiconformal mappings and sharp estimates for the distance to L^\infty in some function spaces

#### Abstract

We provide several estimates which involve the distance to L∞ in some function spaces, the composition operator induced by a quasiconformal mapping and the logarithm of the Jacobian of a quasiconformal mapping. Our results are sharp in the two dimensional case.
