摘要：
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 e(lambda), where. = tau/rho is the ratio of the discrete-time scale tau and the radius rho of the compact space. (C) 2004 Elsevier B.V. All rights reserved.
