Approximations de type Hedberg dans les espaces $W\sp mL\,\log \,L(\Omega)$ et applications. (Approximations of Hedberg type in the spaces $W\sp mL\,\log \,L(\Omega)$ and applications).
(French)
[J] Ann. Fac. Sci. Toulouse, V. Sér., Math. 11, No.2, 67-78 (1990). ISSN 0240-2955

Summary: Two approximation results of the Hedberg type are proved in the Orlicz- Sobolev space $W\sp mL \log L(\Omega)$ when $\Omega$ is an open subset of ${\bbfR}\sp 2$. Applications to the description of the action of some distributions in the dual as well as to some strongly nonlinear elliptic boundary value problems are mentioned.
