  • Article

The energy density of vacuum fluctuations on a multistring space is known to have nonintegrable singularities, hence the total vacuum energy per unit string length diverges. The Casimir effect study is shown to lead to necessary additional regularization corresponding to renormalization of bare values of angle deficits for strings.
