One-Loop Fluctuation Response Along a Constrained Noncommutative Modulus in the Lorentzian IIB Matrix Model
Tetsuyuki Muramatsu
We study a local constrained problem at matrix size in the Lorentzian IIB (IKKT) matrix model and numerically continue a one-dimensional physical modulus. For an exact fixed-…

Off-Shell Supersymmetry Algebra in the Lorentzian IIB Matrix Model: Algebraic Constraints and a -Minkowski-Like Sector
Tetsuyuki Muramatsu
The Lorentzian IIB matrix model provides a non-perturbative framework for emergent spacetime from matrix degrees of freedom. We study whether algebraic consistency constrains such…

Supersymmetric Origin of Four-Dimensional Space-time in the IIB Matrix Model
Tetsuyuki Muramatsu
We investigate the constraints imposed by supersymmetry on the IIB matrix model (IKKT model) by requiring both the closure of the transformations and the satisfaction of the Ward i…
