The particular case of three dimensions, important in string theory, allows us to introduce the notion of gerbes. These offer an appropriate language for describing many significant features of the Strominger-Yau-Zaslow approach to mirror symmetry.Lectures given at the ICTP School on Differential Geometry April 1999Differential GeometryHigh Energy Physics - TheoryAlgebraic Geometry53C25, 53C80, 14J30text
