Coste, Michel; Shiota, Masahiro Nash functions on noncompact Nash manifolds. (English) Zbl 0981.14027 Ann. Sci. Éc. Norm. Supér. (4) 33, No. 1, 139-149 (2000). An affine Nash manifold in \(\mathbb{R}^n\) is a semialgebraic analytic submanifold of \(\mathbb{R}^n\). A Nash mapping between affine Nash manifolds is an analytic mapping with semi-algebraic graph. It was shown by M. Coste, J. M. Ruiz and M. Shiota [Compos. Math. 103, 31-62 (1996; Zbl 0885.14029)] that three important conjectures concerning Nash functions on affine Nash manifolds (separation, global equations and extension conjectures; last two of these conjectures are Nash versions of Cartan’s theorems A and B) are equivalent and that these three conjectures imply the factorization conjecture. An earlier article by M. Coste, J. M. Ruiz and M. Shiota [Am. J. Math. 117, 905-927 (1995; Zbl 0873.32007)] gave a positive answer to the conjectures in the case of compact affine Nash manifolds. In the present article, the authors prove the conjectures for all affine Nash manifolds.
