Query: Quantization of fluctuations in DSR: the two-point function and beyond   We show that the two-point function of a quantum field theory with de Sitter
momentum space (herein called DSR) can be expressed as the product of a
standard delta function and an energy-dependent factor. This is a highly
non-trivial technical result in any theory without a preferred frame. Applied
to models exhibiting running of the dimensionality of space, this result is
essential in proving that vacuum fluctuations are generally scale-invariant at
high energies whenever there is running to two dimensions. This is equally true
for theories with and without a preferred frame, with differences arising only
as we consider higher order correlators. Specifically, the three-point function
of DSR has a unique structure of "open triangles", as shown here.
