摘  要:Deformation theory is a useful tool in the local study of moduli spaces.  The deformation theory of complex manifolds was studied by K. Kodaira and D.C. Spencer, and their theory was adopted by A. Grothendieck to abstract algebraic geometry. I will give an introduction to deformation theory in algebraic geometry. Topics will include:

 1. Deformation theory as the infinitesimal study of moduli spaces
 2. Tangent spaces and obstruction theories
 3. From formal deformations to actual deformations: Grothendieck's existence theorem and M. Artin's approximation theorem  
 4. Typical examples: deformations of varieties, closed subvarieties and vector bundles
 5. Hilbert schemes and moduli space of stable curves
