Abstract. Let be a smooth curve of genus . For any integer the -gonality of is a minimal degree of a line bundle such that . If we assume that the associated map is birational onto its image, then we get the -birational gonality . For we prove the existence of with and . For many genera we prove the existence of with and (both inequalities for the same curve).
