Download e-book for kindle: Algebraic surfaces and holomorphic vector bundles by Robert Friedman

By Robert Friedman

A singular characteristic of the booklet is its built-in method of algebraic floor thought and the learn of vector package deal idea on either curves and surfaces. whereas the 2 topics stay separate in the course of the first few chapters, they develop into even more tightly interconnected because the publication progresses. hence vector bundles over curves are studied to appreciate governed surfaces, after which reappear within the facts of Bogomolov's inequality for reliable bundles, that is itself utilized to check canonical embeddings of surfaces through Reider's process. equally, governed and elliptic surfaces are mentioned intimately, sooner than the geometry of vector bundles over such surfaces is analysed. some of the effects on vector bundles seem for the 1st time in e-book shape, subsidized via many examples, either one of surfaces and vector bundles, and over a hundred workouts forming a vital part of the textual content. aimed toward graduates with a radical first-year path in algebraic geometry, in addition to extra complex scholars and researchers within the components of algebraic geometry, gauge conception, or 4-manifold topology, the various effects on vector bundles can be of curiosity to physicists learning string thought.

The idea of elliptic curves is distinct via its lengthy background and by means of the variety of the equipment which have been utilized in its research. This ebook treats the mathematics procedure in its glossy formula, by using uncomplicated algebraic quantity concept and algebraic geometry. Following a quick dialogue of the required algebro-geometric effects, the publication proceeds with an exposition of the geometry and the formal workforce of elliptic curves, elliptic curves over finite fields, the advanced numbers, neighborhood fields, and international fields.

Then the natural map f : Y → X is unramified, and is a torsor under µn (cf. 1). This implies that KY = f ∗ KX = 0. By the classification of surfaces, Y is an abelian surface. 3). Then A is the Albanese variety of Y . The choice of a base point makes Y an abelian variety isomorphic to A, so that Y is naturally a principal homogeneous space of A. Choose y 0 ∈ Y (k), then we have an isomorphism Y → A that sends y to y − y 0 . Then ρ(g) = g y 0 − y 0 is a continuous 1-cocycle of Gal(k/k) with coefficients in A(k).
