20.1 Sheaf cohomology (Commutative Algebra and Algebraic Geometry)

How can cohomology of sheaves be defined, and what does it measure?
[Typo in the definition of H^p: it should be Ker d^p/Im d^(p-1).]

This lecture is part of a master level course on Commutative Algebra and Algebraic Geometry.
Keywords: sheaf cohomology, ƒČech complex.
Lecturer: Seidon Alsaody, Uppsala University.
