Abstract

We analyze the behaviour of heterotic squashed‐Wess–Zumino–Witten backgrounds under renormalization‐group flow. The flows we consider are driven by perturbation creating extra gauge fluxes. We show how the conformal point acts as an attractor from both the target‐space and world‐sheet points of view. We also address the question of instabilities created by the presence of closed time‐like curves in string backgrounds.
