Relation between chiral central charge and ground-state degeneracy in (2+1)-dimensional topological orders
A bosonic topological order on d-dimensional closed space Σ^{d} may have degenerate ground states. The space Σ^{d} with different shapes (different metrics) form a moduli space M_{Σ^{d}}. Thus the degenerate ground states on every point in the moduli space M_{Σ^{d}} form a complex vector bundle over...
