Course description and aims

We will start with recalling the definitions of almost complex structures and their integrability, and then discuss the functor of points approach to algebraic varieties. Then we will discuss rudiments of symplectic geometry, and compare complex and symplectic geometry using the language of G-structures. After brief introductions to derived categories of coherent sheaves and Fukaya categories, we will discuss several aspects of mirror symmetry. If the time permits, we will also discuss special Lagrangian torus fibrations and tropical geometry.
Mirror symmetry is a mysterious relationship, originally suggested by string theorists, between complex geometry of one space and symplectic geometry of another space, called the mirror of the original space. The aim of this lecture is to discuss similarities and differences between complex and symplectic geometry, and give a gentle introduction to mirror symmetry.
