Wegner-Houghton equation in low dimensions
We consider scalar field theories in dimensions lower than four in the context of the Wegner-Houghton renormalization group equations (WHRG). The renormalized trajectory makes a non-perturbative interpolation between the ultraviolet and the infrared scaling regimes. Strong indication is found that in two dimensions and below the models with polynomial interaction are always non-perturbative in ...

متن کاملScattering for the Beam Equation in Low Dimensions
In this paper, we prove scattering for the defocusing Beam equation utt + ∆u + mu + λ|u|p−1u = 0 in low dimensions 2 ≤ n ≤ 4 for p > 1 + 8/n. The main difficulty is the absence of a Morawetz-type estimate and of a Galilean transformation in order to be able to control the Momentum vector. We overcome the former by using a strategy of Kenig and Merle [6] derived from concentration-compactness id...
متن کاملAdaptive Solution of the Master Equation in Low Dimensions
The master equation satisfied by a probability density function is solved on a grid with a cell size h > 1: A modified master equation is derived for the time development of the average of the density in the larger cells. The accuracy of the approximation is studied and the total probability is conserved. Based on an estimate of the discretization error, the cell size is dynamically adapted to ...
