Phys. Rev. D 63, 043510 (2001) [5 pages]Action of singular instantons of Hawking-Turok typeReceived 15 May 2000; published 30 January 2001 Using the Kaluza-Klein technique we show that a singularity of Hawking-Turok type has a fixed point (bolt) contribution to the action in addition to the usual boundary contribution. Interestingly by adding this contribution we can obtain a simple expression for the total action which is feasible for both regular and singular instantons. © 2001 The American Physical Society URL:
