By Zohar Komargodski and others

We revisit the symmetries of massless two-dimensional adjoint QCD with gauge group *SU(N)*. The dynamics is not sufficiently constrained by the ordinary symmetries and anomalies. Here we show that the theory in fact admits *\sim 2^{2N}* non-invertible symmetries which severely constrain the possible infrared phases and massive excitations. We prove... Show more
