It was proved by Gelfand and Naimark, two Russian mathematicians, in the late 1940s, when 'noncommutative geometry' as such did not yet exist - the term was introduced When one orbit is contained in the closure of another, the orbit space cannot, in a natural way, be given a scheme structure. Noncommutative topology and noncommuta-tive geometry involve applying this principle when the algebra of functions is noncommu-tative. Noncommutative geometry (NCG) is a branch of mathematics concerned with a geometric approach to noncommutative algebras, and with the construction of spaces that are locally presented by noncommutative algebras of functions (possibly in some generalized sense).

We realise the cohomology ring of a flag manifold, more generally the coinvariant algebra of an arbitrary finite Coxeter group W, as a commutative subalgebra of a certain Nichols algebra in the Yetter-Drinfeld category over W. This gives a braided Hopf algebra version of the corresponding Schubert calculus. 1.1 Serre's Proj and Gabriel's spectrum. The suggestion that some new system of statements deserved to be called geometry was a threat. The most important early sources of noncommutative algebraic geometry are the description by Serre of the category of coherent sheaves on a projective variety[S] and the introduction by Gabriel of the injective spectrum of a locally noetherian Grothendieck category. We then study their naive geometry by deformation theory, and prove that this defines noncommutative varieties in a natural way. 9:00 - 9:50. The quasicoherent sheaves have natural analogues in some formalisms of noncommutative algebraic geometry. Algebraic Geometry, Noncommutative Geometry My general area of research is algebraic geometry. dimensional linear algebra'), which provides us in a rigorous way with what is the basic pedagogical example of a 'noncommutative space'. For any smooth associative algebra B, we define its noncommutative cotangent bundle T^*B, which is a basic example of noncommutative symplectic manifold. Tools.
