Hořava–Witten domain wall

In theoretical physics, a Hořava–Witten domain wall is a type of domain wall that behaves as a boundary of the eleven-dimensional spacetime in M-theory.

Petr Hořava and Edward Witten argued that the cancellation of anomalies guarantees that a supersymmetric gauge theory with the E8 gauge group propagates on this domain wall. This fact is important for various relations between M-theory and superstring theory.
