Discrete-Time Quantum Field Theory and the Deformed Super Virasoro Algebra

Original · EN
We show that the deformations of Virasoro and super Virasoro algebra, constructed earlier on an abstract mathematical background, emerge after Wick rotation, within an exact treatment of discrete-time free field models on a circle. The deformation parameter is eλ, where λ=τ/ρ is the ratio of the discrete-time scale τ and the radius ρ of the compact space.
