We review cosmological inflation and its realization in quantum field theory and string theory. We describe two intertwined approaches to the physics of inflation: from the bottom up in effective field theory, and from the top down in string theory.

This volume highlights the interface between string theory and algebraic geometry. The topics covered include manifolds of special holonomy, supergravity, supersymmetry, D-branes, the McKay correspondence and the Fourier-Mukai transform.

These notes give an introduction to string theory for students and interested researches. No previous knowledge of string theory is assumed. The focus is on gravitational aspects and we explain how gravity is described in string theory.
