“…Banach contraction principle has been extended in many different directions, see [2][3][4][5][6][7][8][9][10]. The notion of modular spaces, as a generalize of metric spaces, was introduced by Nakano [11] and was intensively developed by Koshi, Shimogaki, Yamamuro [11][12][13] and others. Further and the most complete development of these theories are due to Luxemburg, Musielak, Orlicz, Mazur, Turpin [14][15][16][17][18] and their collaborators.…”
