By Qing Liu,Reinie Erne

This e-book is a common advent to the speculation of schemes, via purposes to mathematics surfaces and to the idea of aid of algebraic curves.

The first half introduces easy gadgets akin to schemes, morphisms, base switch, neighborhood houses (normality, regularity, Zariski's major Theorem). this can be by way of 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 concept. the 1st half ends with the concept of Riemann-Roch and its program to the learn of gentle projective curves over a field.
Singular curves are taken care of via an in depth examine of the Picard group.

The moment half starts off with blowing-ups and desingularisation (embedded or now not) of fibered surfaces over a Dedekind ring that leads directly to intersection thought on mathematics surfaces. Castelnuovo's criterion is proved and likewise the lifestyles of the minimum typical version. This ends up in the research of aid of algebraic curves. The case of elliptic curves is studied intimately. The ebook concludes with the funadmental theorem of solid relief of Deligne-Mumford.

The ebook is basically self-contained, together with the required fabric on commutative algebra. the must haves are consequently few, and the e-book should still swimsuit a graduate pupil. It comprises many examples and approximately six hundred exercises.
