Abstract

Non-commutative (NC) gauge theories on coordinate-dependent space-time provide a robust framework to investigate deviations from classical physics, particularly when the non-commutativity parameter $\Theta^{ab}(x)$ varies with space-time coordinates. Using the $L_\infty$-algebra formalism, these theories encode higher-order corrections and ensure consistency through generalized Jacobi identities. This project extends the graded vector space $V = V_0 \oplus V_1$ to include $V_2$, the field strength tensor $\mathcal{F}_{\mu\nu}$ is incorporated, capturing the dynamical content of NC gauge theories. The $L_\infty$-bootstrap method systematically constructs these deformations, maintains gauge covariance, and ensures algebraic closure. This unified formalism provides a powerful tool to explore the algebraic, geometric, and physical implications of NC gauge theories. (AU)
