Abstract
In this thesis work, we present a systematic classification of four dimensional rank-1 N=2 superconformal field theories (SCFTs). The analysis is based on extracting the low energy properties of N=2 SCFTs through the study of the structure of their Coulomb branch geometries. The original work of Seiberg and Witten provided the key to interpret features of $\cN=2$ theories in terms of geometrical objects. Generalizing from that seminal work, we show how a systematic description of rank-1 N=2 SCFTs is possible. An important property to consider is that a scale invariant Coulomb Branch geometry does not fully characterize a theory; we have to introduce a set of deformations, that still preserve the N=2 supersymmetry structure, together with consistency conditions for them, to distinguish theories sharing the same scale invariant behavior. The main outcome of our study is to provide a classification of the flavor algebras for the theories corresponding to the geometries we study. We carry this out in two ways. The first, called the algebraic approach, directly extends the work of Seiberg and Witten (and subsequent research). The second, topological approach, is a field theoretic extension of work originated in the string theory literature. In either case, the preexisting research provided only a partial answer to our problem, essentially describing only the subset of all the possible geometries that we call the ``maximal deformations''. Our construction is to be contrasted and in fact complements the conformal bootstrap framework, which instead of studying the low energy properties of these theories relies on the constraints of the full conformal symmetry of the microscopic theory.
