Vanishing of the $H^{3}$ obstruction for time-reversal symmetry in (2+1)D abelian bosonic TQFTs

Ippo Orii

In $(2 + 1)$ -dimensional topological quantum field theories (TQFTs), the action of a global symmetry group on the anyon system is one of the central topics of research. Owing to the…

Generalization of anomaly formula for time reversal symmetry in (2+1)D abelian bosonic TQFTs

Ippo Orii

We study time-reversal symmetry in $(2 + 1)$ D abelian bosonic topological phases. Time-reversal anomalies in such systems are classified by $Z_{2} \times Z_{2}$ symmetr…

On dimensions of (2+1)D abelian bosonic topological systems on non-orientable manifolds

Ippo Orii

We give a framework to describe abelian bosonic topological systems with parity symmetry on a torus in terms of the projective representation of $G L (2, Z)$ . However, this i…
