An alternative to exact renormalization equations
Jean Alexandre
An alternative point of view to exact renormalization equations is discussed, where quantum fluctuations of a theory are controlled by the bare mass of a particle. The procedure is…

A note on Liouville theory
Jean Alexandre
An exact differential equation is derived for the evolution of the Liouville effective action with the mass parameter. This derivation is based on properties of the exponential pot…
