Description
We consider 4d N=1 Lagrangians dual to N=2 Argyres-Douglas models. The N=1 gauge theories have chiral ring operators with small r-charge, that violate the unitarity bound. We propose a general procedure to complete such theories, isolating the infrared interacting SCFT. This allows to reduce the dualities to 3d and find two physical interpretations: the 'Abelianization duality' and its 3d mirror, the 'sequential confinement RG flow'. Based on https://arxiv.org/abs/1706.02225, https://arxiv.org/abs/1706.04949, https://arxiv.org/abs/1707.05113.
