Description
Remarks 1 and 2 focus on half-BPS line defects in four-dimensional field theories with N=2 supersymmetry. Remark 1 concerns a minor, but intriguing, gap in the classification of line defects in Lagrangian theories of class S. Remark 2 concerns computations of ``VEV's'' of line defects on R3 x S1. Remark 3 discusses some hypothetical new N=2 d=4 superconformal theories.
