Abstract

If XX is a manifold then the set C(X)C^\infty(X) of smooth functions f:XRf:X\to\mathbb R is a CC^\infty-ring, a rich algebraic structure with many operations. CC^\infty-schemes are schemes over CC^\infty-rings, a way of using Algebro-Geometric techniques in Differential Geometry. They include smooth manifolds, but also many singular and infinite-dimensional spaces. They have applications to Synthetic Differential Geometry, and to derived manifolds. In this book, a sequel to the second author's monograph on CC^\infty-algebraic geometry arXiv:1001.0023, we define and study new categories of CC^\infty-rings with corners and CC^\infty-schemes with corners, which generalize manifolds with corners in the same way that CC^\infty-rings and CC^\infty-schemes generalize manifolds. These will be used in future work as the foundations of theories of derived manifolds and derived orbifolds with corners. This book is based on the PhD thesis of the first author, supervised by the second author.
