In this mini-course we will discuss the classification of simple weight modules for the Lie algebra of vector fields on a torus. We will begin with the elementary constructions of representations of a geometric nature - modules of tensor fields on a torus. We will discuss the question of irreducibility of these modules and the exceptional nature of the modules in the de Rham complex. The second family of irreducible modules that we introduce will be the class of bounded modules. We will present their vertex operator realizations and explain the construction of the chiral de Rham complex. Finally, we will discuss the proof of the classification theorem for the irreducible weight modules for the Lie algebra of vector fields on a torus.
