设X是Cpn−1中的正则不可约簇,Y是C中的相伴齐次簇,N是Cpn−1的万能丛对X的限制.本文利用上同调群H(X,O(N))计算了Y上1∂p≤的L意义下的≤∞方程的解的障碍.这样,如果更精确地指定了X,例如,如果X等同于CP或椭圆曲线,则可以显式识别障碍物。
Let X be a regular irreducible variety in CPn−1, Y the associated homogeneous variety in C, and N the restriction of the universal bundle of CPn−1 to X. In the present paper, we compute the obstructions to solving the ∂-equation in the L-sense on Y for 1 ≤ p ≤ ∞ in terms of cohomology groups H(X,O(N)). That allows to identify obstructions explicitly if X is specified more precisely, for example if it is equivalent to CP or an elliptic curve.
