У оквиру семинара Групе за гравитацију, честице и поља у петак, 17. октобра 2025. године у 11:15 у сали 360 Института за физику у Београду, Ђорђе Богдановић (Физички факултет, Универзитет у Београду) одржаће предавање:

Noncommutative Scalar Quantum Field Theory

САЖЕТАК:

We study a scalar field theory with cubic interaction, quantized using the homological quantization approach within an algebraic framework. Noncommutativity is introduced in two distinct ways, and the resulting theories are compared. In the first case, the underlying L-infinity algebra of the field theory remains undeformed (commutative), while the interaction is defined via the standard star product, yielding results equivalent to those obtained through the path integral approach. In the second case, both the interaction and the underlying L-infinity algebra are twist-deformed, giving rise to a different noncommutative field theory known as braided field theory.
