Hua, Zheng Jian, Family of Analytic Mappings Between Ultrahyperelliptic Surfaces, Acta Mathematica Sinica, New Series Chinese Journal of Mathematics, 9(4), 1993, pp. 414-420
The purpose of this paper is to investigate the structure of the family of projections of analytic mappings between ultrahyperelliptic surfaces (one kind of algeboid surfaces), by in- troducing the linear differential equation with polynomial coefficients, and to get a generalization of one result of Ozawa's.
