Appears in collection : Not Only Scalar Curvature Seminar

This introduction to boundary value problems for Dirac operators will not focus on analytic technicalities but rather provide a working knowledge to anyone who wants to apply the theory, i.e. in the study of positive scalar curvature. We will systematically study "elliptic boundary conditions" and discuss the following topics:
* typical examples of such boundary conditions * regularity of the solutions up to the boundary * Fredholm property and index computation * geometric applications
