Abstract: We study BPS spectrum of four-dimensional N=2 superconformal field theory of Argyres-Douglas type, obtained via twisted compactification of six-dimensional A_N (2,0) theory on a sphere with an irregular puncture, by using spectral networks. We give strong evidences of the equivalence of N=2 superconformal field theories from different rank six-dimensional theories, by systematically comparing the chamber structure and wall-crossing phenomena. This talk is based on the joint work with Kazunobu Maruyoshi and Wenbin Yan.
