Description
Scattering amplitudes can be (often) calculated via certain special functions
called multiple polylogarithms / their generalizations.
I will introduce h-deformation of these functions.
The simplest of them is the quantum dilogarithm function, which comes with the
quantum deformation of the Abel's five term relation, and has many applications in Math and Physics.
These h-deformations suggest that the scattering amplitudes in general should also have natural h-deformations.
