Title · changed: Revision 1: Does BFSS matrix theory recover eleven-dimensional Lorentz invariance; Revision 2: Does BFSS matrix theory recover eleven-dimensional Lorentz invariance?
Plain: A quantum mechanics of N by N matrices is conjectured to equal M-theory when N becomes infinite. Whether it reproduces full eleven-dimensional relativity beyond protected calculations is unknown.
Precise: The BFSS model, $SU(N)$ maximally supersymmetric quantum mechanics, is conjectured to describe M-theory in light-cone frame as $N \to \infty$ with $p^+ = N/R$. Determine whether its amplitudes (graviton scattering) reproduce 11D Lorentz-invariant results beyond terms protected by supersymmetry, i.e. whether the large-N limit at fixed $p^+$ exists and is boost invariant.
Settled by: A large-N computation of an unprotected scattering amplitude in BFSS compared with 11D supergravity or M-theory.
Kind: well-posed
Answer type: yes-no
References: (empty)
Literature status: partially-resolved
Status note: Agreement holds for supersymmetry-protected terms (1997-1998); work on soft theorems and scattering in BFSS (2023-2025) tests the large-N limit without a full answer.
Posed since: 1996
