## Index of Algebraic Geometry

Algebraic Geometry (AG), and non-commutative geometry/. On the other hand, there are also close ties between algebraic geometry and number theory.

### Disciplines in algebraic geometry

1. Birational geometry, Dedekind \htmladdnormallink{domains {http://planetphysics.us/encyclopedia/Bijective.html} and Riemann-Roch theorem}
2. Homology and cohomology theories
3. Algebraic groups: Lie groups, matrix group schemes,group machines, linear groups, generalizing Lie groups, representation theory
4. Abelian varieties
5. Arithmetic algebraic geometry

10. higher dimensional algebra (HDA)
11. Quantum Algebraic Topology (QAT)
12. Quantum Geometry
13. computer algebra systems; an example is: explicit projective resolutions for finitely-generated modules over suitable rings

### Cohomology

Cohomology is an essential theory in the study of complex manifolds. computations in cohomology studies of complex manifolds in algebraic geometry utilize similar computations to those of cohomology theory in algebraic topology: spectral sequences, excision, the Mayer-Vietoris sequence, etc.

1. cohomology groups are defined and then cohomology functors associate Abelian groups to sheaves on a scheme; one may view such Abelian groups them as cohomology with coefficients in a scheme.
2. Cohomology functors
3. fundamental cohomology theorems
4. A basic type of cohomology for schemes is the sheaf cohomology
5. Whitehead groups, torsion and towers
