Explicit Examples on Conformal Invariance
M. Hortacsu
We study examples where conformal invariance implies rational critical indices, triviality of the underlying quantum field theory and emergence of hypergeometric functions as solut…

An Extension of Multiple Cosmic String Solution: A Proposal
M. Hortacsu, N. Ozdemir
We extend the work done for cosmic strings and show that for a more general class of locally flat metrics the one loop calculation do not introduce any new divergences to the VEV o…

Do Cosmic Strings Give Rise to Vacuum Fluctuations ?
A. H. Bilge, M. Hortacsu, N. Ozdemir
The role of the identification of the vacuum and non-vacuum space-times in the computation of vacuum fluctuations in the presence of a cosmic string is discussed and an alternative…
