有理曲线
rational curve
有理曲线[rati田目curve;p叫.0”场妞aH即抓朗] 定义在代数闭域k上的一维代数簇(司罗bnucva-riety)，它的有理函数域是k上1次纯超越扩张(tran-scendental extension).非奇异完全有理曲线同构于射影直线P’.完全的奇异曲线X是有理的，当且仅当它的几何亏格g等于零，也就是说，X上没有正则微分形式. 当火为复数域C时，(仅有的)非奇异完全有理曲线x是Ri~nn球面C口{的}· B皿.C. Ky几拟oB撰【补注】在经典文献中有理曲线亦称单行曲线(u苗-cursal eurve). 如果X定义在一个不必代数闭的域k上，且X在k上双有理等价于P止，则称X为k有理曲线(无-rational eurve).
