We consider scalar field theory with space and space-time-dependent non-commutativity. In perturbation theory, we find that the structure of the UV/IR mixing is quite different from cases with constant non-commutativity. In particular, UV/IR mixing becomes intertwined in an interesting way with violations of momentum conservation.

Holography with Null Boundaries
hep-th 2025-06 conditional novelty 7.0 of 10

D1-D5-F1 string theory in a non-commutative decoupling limit yields a holographic correspondence for spacetimes with a null boundary, interpolating between AdS3 and a six-dimensional asymptotic metric.
