Trans-Planckian Scale and Krein Space Quantization    [PDF]

A. Sojasi, M. Mohsenzadeh

In this work, Krein space quantization method is applied to eliminate the
Ultraviolet divergence of Green functions. This paper shows that the power
spectrum of scalar field fluctuations can be calculated in the limit of short
distance physics, trans-Planckian physics, without using the usual
re-normalization process.
