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…
