Stratifications,nches of algebraic curves are studied in Section 5. Semi-algebraic versions of Sard’s and Bertini’s theorems are contained in Section 6. The last section is devoted to Whitney’s conditions . and ...Throughout this chapter, R denotes a real closed field.ornithology 发表于 2025-3-29 07:13:36
Real Places,lgebraic curves can be considered as points of the real spectrum. We finish the chapter with a glimpse of the theory of fans, presenting a few applications to the study of basic semi-algebraic sets..Throughout this chapter, R is a fixed real closed field.昆虫 发表于 2025-3-29 13:45:42

Witt Rings in Real Algebraic Geometry,we prove that the morphism .(.(.)) .(..(.)), induced by the inclusion .(.) ..(.), is surjective. This is part of the result of Brumfiel, which asserts that this morphism is actually an isomorphism.免除责任 发表于 2025-3-30 03:11:15
