Some Issues related to Conformal Anomaly Induced Effective Action
Sergio Zerbini
Some issues related to quantum anomaly induced effects due to matter are considered. Explicit examples corresponding to quantum creation of d4 dilatonic AdS Universe and of d2 dila…
Consistent, covariant and multiplicative anomalies
Guido Cognola, Sergio Zerbini
It is shown that the multiplicative anomaly in the vector-axial-vector model, which apparently has nothing to do with the breaking of classical current symmetries, nevertheless is…
Is the multiplicative anomaly relevant ?
Emilio Elizalde, Antonio Filippi, Luciano Vanzo +1
In a recent work, S. Dowker has shed doubt on a recipe used in computing the partition function for a matrix valued operator. This recipe, advocated by Benson, Bernstein and Dodels…
Is the multiplicative anomaly dependent on the regularization ?
Emilio Elizalde, Antonio Filippi, Luciano Vanzo +1
In a recent work, T.S. Evans has claimed that the multiplicative anomaly associated with the zeta-function regularization of functional determinants is regularization dependent. We…
Zeta-function on the generalised cone
Guido Cognola, Sergio Zerbini
The analytic properties of the zeta-function for a Laplace operator on a generalised cone are studied in some detail using the Cheeger's approach and explicit expressions are given…
Mellin Transform Techniques for Zeta-Function Resummations
E. Elizalde, S. Leseduarte, S. Zerbini
Making use of inverse Mellin transform techniques for analytical continuation, an elegant proof and an extension of the zeta function regularization theorem is obtained. No series…
