by
Sidi Mohammed Bouguima
University of Tlemcen, Algeria
Coauthors: A. Yechoui

Using upper and lower solution method, we obtain the existence of at least one solution for the following problem:
-\Deltau
=
\lambdaa(x)f(u)\text   in \Omega
u
=
0\text   on \partial \Omega

where a(.) is a function which can change sign.
