Download E-books Algebraic Geometry and Arithmetic Curves (Oxford Graduate Texts in Mathematics) PDF

By Qing Liu

This new-in-paperback variation presents a common creation to algebraic and mathematics geometry, beginning with the idea of schemes, through purposes to mathematics surfaces and to the idea of relief of algebraic curves.

The first half introduces uncomplicated gadgets resembling schemes, morphisms, base swap, neighborhood houses (normality, regularity, Zariski's major Theorem). this is often through the extra worldwide element: coherent sheaves and a finiteness theorem for his or her cohomology teams. Then follows a bankruptcy on sheaves of differentials, dualizing sheaves, and Grothendieck's duality thought. the 1st half ends with the concept of Riemann-Roch and its program to the learn of gentle projective curves over a box. Singular curves are handled via a close research of the Picard group.

The moment half begins with blowing-ups and desingularization (embedded or now not) of fibered surfaces over a Dedekind ring that leads directly to intersection conception on mathematics surfaces. Castelnuovo's criterion is proved and likewise the life of the minimum usual version. This ends up in the research of relief of algebraic curves. The case of elliptic curves is studied intimately. The booklet concludes with the basic theorem of strong relief of Deligne-Mumford.

This ebook is largely self-contained, together with the mandatory fabric on commutative algebra. the must haves are few, and together with many examples and nearly six hundred workouts, the ebook is perfect for graduate students.

Download E-books Algebraic Curves and Riemann Surfaces (Graduate Studies in Mathematics, Vol 5) PDF

By Rick Miranda

During this ebook, Miranda takes the procedure that algebraic curves are top encountered for the 1st time over the complicated numbers, the place the reader's classical instinct approximately surfaces, integration, and different innovations should be introduced into play. for this reason, many examples of algebraic curves are provided within the first chapters. during this manner, the publication starts off as a primer on Riemann surfaces, with advanced charts and meromorphic features taking middle degree. however the major examples come from projective curves, and slowly yet without doubt the textual content strikes towards the algebraic class. Proofs of the Riemann-Roch and Serre Duality Theorems are awarded in an algebraic demeanour, through an version of the adelic facts, expressed thoroughly when it comes to fixing a Mittag-Leffler challenge. Sheaves and cohomology are brought as a unifying equipment within the latter chapters, in order that their application and naturalness are instantly visible. Requiring a historical past of a one semester of advanced variable! idea and a 12 months of summary algebra, this can be a superb graduate textbook for a second-semester path in complicated variables or a year-long direction in algebraic geometry.

By Barbara Fantechi, Nitin Nitsure

Alexander Grothendieck's innovations became out to be astoundingly strong and effective, actually revolutionizing algebraic geometry. He sketched his new theories in talks given on the Séminaire Bourbaki among 1957 and 1962. He then amassed those lectures in a sequence of articles in Fondements de los angeles géométrie algébrique (commonly often called FGA). a lot of FGA is now universal wisdom. despite the fact that, a few of it really is much less popular, and just a couple of geometers are conversant in its complete scope. The aim of the present publication, which resulted from the 2003 complex university in simple Algebraic Geometry (Trieste, Italy), is to fill within the gaps in Grothendieck's very condensed define of his theories. The 4 major topics mentioned within the ebook are descent idea, Hilbert and Quot schemes, the formal life theorem, and the Picard scheme. The authors current whole proofs of the most effects, utilizing more recent principles to advertise figuring out each time helpful, and drawing connections to later advancements. With the most prerequisite being an intensive acquaintance with simple scheme idea, this ebook is a useful source for someone operating in algebraic geometry.
