In this paper, we introduce the notions of nonlinear contractions in modular spaces and establish their fixed points theorems in modular spaces.

We will start with a brief recollection of basic concepts and facts in modular spaces and modular metric spaces (see [14, 15, 27 29] for more details).

In 1950 [1], Nakano initiated the theory of modular spaces and further it was generalized and redefined by Musielak and Orlicz [2, 3] in 1959.

In 2015, Jleli and Samet [1] introduced a very interesting concept of a generalized metric space, which covers different well-known metric structures including classical metric spaces, b-metric spaces, dislocated metric spaces, modular spaces, and so on.

Recently several years, the researchers in [3 14] and others continued the study of Rhoades and Branciari, proved some fixed point and common fixed point theorems for various generalized weakly contraction mappings and contractive mappings of integral type in complete metric spaces, Banach spaces, modular spaces and symmetric spaces.

When ρ is convex modular, then Vert xVert_{rho}=infbiggl{ alpha>0;rhobiggl(frac{x}{alpha} biggr)leq1biggr} defines a norm on the modular space (X_{rho}), and this is called the Luxemburg norm.
