- n. A topological space in which every small enough neighborhood is homeomorphic to a quotient of real space by the action of a finite group.
It has something to do with maximal supersymmetry, orbifold compactifications, Calabi-Yau spaces and other matters a bit beyond the scope here.
Maldecena and Lin conjecture that orbifold solutions in String Theory could decay into these soliton states as tachyons condense.
A test against some explicit orbifold calculations works.
Did Beethoven’s brain really exhibit patterns of orbifold compactification of D2-branes?
Another test passes: a comparison with Wilson loop vevs in a dual large N Chern-Simons theory (on a Z_p orbifold of
