Abstract

We prove an existence result of solutions for nonlinear elliptic unilateral problems having natural growth terms and L1 data in Musielak-Orlicz-Sobolev space W1Lφ, under the assumption that the conjugate function of φ satisfies the ∆2-condition.

Highlights

  • On Orlicz spaces and in the variational case, it is well known that Gossez and Mustonen solved in [20] the following obstacle problem u ∈ Kφ

  • In the framework of variable exponent Sobolev spaces, Azroul, Redwane and Yazough have shown in [6] the existence of solutions for the unilateral problem associated to (1.1) where the second member f is in L1(Ω)

  • In the setting of Musielak-Orlicz spaces and in variational case, Benkirane and Sidi El vally [12] proved the existence of solutions for the obstacle problem (1.2), they generalized the work of Gossez and Mustonen in [20]
