Sažetak

It has been shown that within the framework of the fractional spectral triplet action in noncommutative geometry, constructed recently by the author in the sense of Erd´elyi-Kober fractional integral considerations, more quantum vacuum energy per a single mode is generated in the background of the spatially flat FriedmannRobertson-Walker spacetime geometry. Our analyses are based on Broda et al. formalism which uses the coordinate gauge freedom transformations in the Euclidean version of the formalism of effective action. The result is estimated for a particular value of the fractional integral exponent which corresponds to the Raspini fractional Dirac operator of the order 2/3.
