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 Erdélyi-Kober
fractional integral considerations, more quantum vacuum energy
per a single mode is generated in the background of the
spatially flat Friedmann-Robertson-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.
