BFSS
BFSS refers to the BFSS matrix model, a proposal by Banks, Fischler, Shenker, and Susskind for a nonperturbative definition of M-theory in the infinite momentum frame. Introduced in 1996, it describes the quantum mechanics of N by N Hermitian matrices and is built as the dimensional reduction of ten-dimensional super Yang–Mills theory to one time dimension. The model is formulated in terms of nine bosonic matrices X^i(t) (i = 1,…,9) representing spatial coordinates and their fermionic superpartners, forming a supersymmetric quantum mechanics with 16 supercharges.
Physically, the BFSS model arises as the low-energy effective theory on the worldvolume of D0-branes in type
The central claim of the BFSS conjecture is that, in the appropriate discrete light-cone quantization limit
