Quasicontraction mappings in modular spaces without Delta(2)-condition

As a generalization to Banach contraction principle, Ciric introduced the concept of quasi-contraction mappings. In this paper, we investigate these kinds of mappings in modular function spaces without the Delta(2)-condition. In particular, we prove the existence of fixed points and discuss their uniqueness.
