WebComputational Algebraic Geometry (CAG for short) is a branch of mathematics that studies computational approaches in algebraic geometry. Speci cally CAG aims to develop algorithms for computing mathematical objects such as the locus of the zeros of multivariate systems, singularities of algebraic varieties and the cohomology groups of coherent ... Webwill be devoted to sheaf theory, which we will develop with differential geometry as motivation. A powerful method in algebraic geometry is sheaf cohomology, which gives us tools for defining invari-ants. The construction of sheaf cohomology through the derived functor approach will be discussed in this chapter. blackie weather WebJun 10, 2024 · Introductory level but excellent textbooks.

They are used particularly in algebraic geometry and related fields. A key result known as Chevalley's theorem in algebraic geometry shows that the image of a constructible set is constructible for an important class of mappings (more …

In algebraic geometry, an etale sheaf on a Noetherian scheme is called constructible if the scheme has a finite stratification by locally closed subschemes such that the pullback of the sheaf to each of the subschemes is lcc (locally constant constructible). This definition seems to make sense both for sheaves of abelian groups and sheaves ...
