Sheaves, Cohomology and Vector Bundles
 The course will be held in English.
 The lecture takes on Monday 10:15  11:45 in SR 10, Geb. E2 4,
and on Thursday 12:30  14:00 in SR 9, Geb. E 2 4.  There will be exercise session on Thursday 10:15  11:45 in SR 10, once every two weeks.
The main objective of the lecture is to learn and be familiar with sheaves, vector bundles, and sheaf cohomology, which appear as key materials in algebraic topology and algebraic geometry. A secondary objective is to learn basic algebraic curve theory and Ulrich sheaves.
Very basic knowledge of commutative algebra and algebraic geometry is recommended.
Tentative topics containing:
presheaf, sheaf, divisor, line bundle, vector bundle, projective morphism, derived functor, sheaf cohomology, Čech cohomology, Serre duality, RiemannRoch formula, RiemannHurwitz formula, Petri theorem, Green's (2g+1+p)theorem, canonical curve, determinantal representation, Ulrich sheaf
