笛沙格及其射影几何学奠基性工作

Desargues and His Fundamental Work on Projective Geometry

17世纪法国数学家笛沙格在射影几何方面的工作具有创造性成就。然而 ,由于笛沙格本人射影几何手稿写作手法晦涩难懂及其客观历史原因 ,导致他的学术思想的传播障碍以致长期淹没无闻。本文试图对笛沙格生平、学术活动、射影几何思想的形成背景及其射影几何的奠基性工作加以详细研究和评述 ,恢复笛沙格对射影几何学这一门现代数学学科分支的奠定性贡献的应有历史地位。

Desargues who was a French mathematician in 17th century had made creative achievement in the aspect of projective geometry. This paper attempts to study and comment in detail on Desargues' life, academic activities, and his historic position of fundamental contribution in the field of projective geometry.
