正可构函数对欧拉示性数和维数的积分
Integration of positive constructible functions against Euler characteristic and dimension
摘要:
根据R. Cluckers和F. Loeser [Fonctions constructible et integration motivic I,C. R.数学学院Sci. Paris 339(2004)411 - 416]关于动机整合,我们在全局次分析背景下发展了正可构造函数的直接图像形式主义。这种形式主义推广到任意的一阶逻辑模型,并说明了几个例子上的p-adics,Presburger结构和O-最小的扩展组。在此基础上,定义了Radon变换,并证明了相应的反演公式.
英文摘要:
Following recent work of R. Cluckers and F. Loeser [Fonctions constructible et integration motivic I, C. R. Math. Acad. Sci. Paris 339 (2004) 411 - 416] on motivic integration, we develop a direct image formalism for positive constructible functions in the globally subanalytic context. This formalism is generalized to arbitrary first-order logic models and is illustrated by several examples on the p-adics, on the Presburger structure and on o-minimal expansions of groups. Furthermore, within this formalism, we define the Radon transform and prove the corresponding inversion formula.
