摘要: 通过扭映射π:CP7→ HP3构造出HP3中10族共形极小曲面的例子.根据Eells和Wood在1983年得到的结论,水平调和映射在淹没映射下的像仍然是调和的.首先给出CP7中水平全纯曲面在局部下的一个分类定理.基于该分类定理以及Eells和Wood的结论,利用扭映射,构造出HP3中的共形极小曲面.

Abstract: In this paper, we construct ten families of conformal minimal surfaces immersed into HP3 by the twistor map π:CP7→HP3. The construction is based on Eells and Wood's conclusion in 1983 that the projection of a horizontal harmonic map is also harmonic. Firstly, we give a characterization theorem for horizontal holomorphic surfaces in CP7. By this theorem and Eells and Wood's conclusion, we get some conformal minimal surfaces immersed into HP3 by the twisted map.

Key words: quaternionic projective space, conformal minimal surface, twistor map
