Spinors have important applications in differential geometry and general relativity. Unlike the case of tensor analysis much of spinor analysis is masked by representation theory jargons, which vary considerably with dimension and metric signature, thus becoming difficult and time consuming for analysts. Although tensors are also elements of representation spaces, with tensors we do much computation without going deep into representation theory. Aim of this course is to learn performing similar applications with spinors. Starting with SU(2) spinors on 3-dimensional Riemannian manifolds from very basics, we learn to do calculation in local coordinates, study positive mass theorem, and spinor representation of surfaces in Euclidean 3-space. We study spinors on Riemannian 4-manifolds and spend few hours on CP2 as an example of non-spin manifold. Finally we study SL(2,C) spinors in 3+1 space-times. The course is suitable for both graduate and senior level undergraduate students.
