Spiky projective planes

Research output: Contribution to journalArticlepeer-review


It has been suggested that the so-called c=1 barrier in subcritical string theory is the result of a Kosterlitz-Thouless transition in the associated Liouville theory. We show that arguments analogous to those used to imply a transition on orientable worldsheets may also be applied to non-orientable worldsheets such as the real projective plane. This means that the barrier is still present for such worldsheets.
