实射影空间之间的单纯形分解与代数映射空间

Simplicial resolutions and spaces of algebraic maps between real projective spaces

Andrzej Kozlowski, Kohhei Yamaguchi

摘要:

本文证明了空间$\tilde{A}_{d}(m,n)$是由$(m+1)$变元的实系数齐次多项式的$d$-元组的所有实射影类组成的,除零外没有公共实根,具有与从$m$维实射影空间$\RP^m$到$n$维实射影空间$\RP^n$直到维数%的连续映射的空间$ \Map(\RP^m,\Bbb \RP^n)$相同的同调性尺寸小于$(n-m)(d+1)-1$。这大大改进了\cite{AKY1}的主要结果。

英文摘要:

We show that the space $\tilde{A}_{d}(m,n)$ consisting of all real projective classes of $(n+1)$-tuples of real coefficients homogeneous polynomials of degree $d$ in $(m+1)$ variables, without common real roots except zero, has the same homology as the space $ \Map(\RP^m,\Bbb \RP^n)$ of continuous maps from the $m$-dimensional real projective space $\RP^m$ into the $n$ real dimensional projective space $\RP^n$ up to dimension %in dimensions smaller than $(n-m)(d+1)-1$. This considerably improves the main result of \cite{AKY1}.
