Ballico, Edoardo; Homma, Masaaki An inequality of Clifford indices for a finite covering of curves. (English) Zbl 1073.14528 Bol. Soc. Bras. Mat., Nova Sér. 32, No. 2, 145-147 (2001). Summary: We prove that for a finite covering of curves the Clifford index of the source is at least that of the target.
