Query: Equivalence Classes of Boundary Conditions in SU(N) Gauge Theory on
  2-dimensional Orbifolds   We study equivalence classes of boundary conditions in an SU(N) gauge theory
on six-dimensional space-time including two-dimensional orbifold. For five
kinds of two-dimensional orbifolds $S^1/Z_2 \times S^1/Z_2$ and $T^2/Z_m$
$(m=2,3,4,6)$, orbifold conditions and those gauge transformation properties
are given and the equivalence relations among boundary conditions are derived.
The classification of boundary conditions related to diagonal representatives
is carried out using the equivalence relations.
