[institut] [phys4phys] GPF seminar, 17th October

[Maja Buric]

Dear colleagues,

the next GPF seminar will be given by Djordje Bogdanovic on
Friday 17th of October at 11.15, small seminar room on
the second floor, at the IPB.


Title: Noncommutative Scalar Quantum Field Theory

Abstract: 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.
