We formulate scalar electrodynamics in the braided L ∞ $L_\infty$ -algebra formalism and study its perturbative expansion in the algebraic framework of Batalin–Vilkovisky quantization. We also confirm that UV/IR mixing is absent at one-loop order in this noncommutative field theory, and that the non-anomalous Ward-Takahashi identities for the braided gauge symmetry are satisfied.

We formulate scalar field theories in a curved braided L ∞ $L_\infty$ -algebra formalism and analyse their correlation functions using Batalin–Vilkovisky quantization. We perform detailed calculations in cubic braided scalar field theory up to two-loop order and three-point multiplicity. The divergent tadpole contributions are eliminated by a suitable choice of central curvature for the L ∞ $L_\infty$ -structure, and we confirm the absence of UV/IR mixing.

Fact CheckedChallenging economic conditions often force electricity companies to make difficult decisions about lifting prices, slashing costs or exiting their business. Rising energy costs can significantly affect the bottom line of retailers, especially emerging brands with smaller customer bases compared to the big three providers. This Canstar Blue article explores what happens to customers when their energy provider permanently closes.
