二次不等式
Systems of Quadratic Inequalities
摘要:
本文给出了一个谱序列,它有效地计算了RP^n中由一组二次不等式定义的闭半代数子集的贝蒂数,并给出了RP^n中包含该子集所引起的同调同态的象.我们并不局限于谱序列的E_2项,而是给出了微分d_2的一个简单的显式公式。
英文摘要:
We present a spectral sequence which efficiently computes Betti numbers of a closed semi-algebraic subset of RP^n defined by a system of quadratic inequalities and the image of the homology homomorphism induced by the inclusion of this subset in RP^n. We do not restrict ourselves to the term E_2 of the spectral sequence and give a simple explicit formula for the differential d_2.
