1) Projective variety
射影簇
1.
Let X be an n dimensional projective variety.
设X是n维光滑射影代数簇,如果X不是极小模型,则存在X到一正规射影簇Y的满态射f:X→Y,集合E={x∈X|f在x点不是局部同构的}称为f的例外集。
2) quasiprojective variety

3) set of projective zeros
射影零簇
4) projective variety
射影代数簇
1.
Let X be a n dimensional projective variety,x be a fixed point in X,and let C_t(X,_X(1)) be the set of rational curves C of degree t passing through x in X,p_t(X)=dimC_t(X,_X(1)) for any positive integer.
设X是n维射影代数簇,取定X中一点x,设Ct(X,X(1))表示X中的过x点的t次有理曲线的集合,pt(X)=d imCt(X,X(1))。
