Analytic signal in many dimensions
In this paper we extend analytic signal method to the functions in many dimensions. First it is shown how to obtain separate phase-shifted components and how combine them to obtain signal's envelope, instantaneous frequencies and phases in many dimensions. Second, we show that phase-shifted components may be obtained by positive frequency restriction of the Fourier transform defined in the alge...
متن کاملCorrelation Functions of a Conformal Field Theory in Three Dimensions
We derive explicit forms of the two–point correlation functions of the O(N) non-linear sigma model at the critical point, in the large N limit, on various three dimensional manifolds of constant curvature. The two–point correlation function, G(x, y), is the only n-point correlation function which survives in this limit. We analyze the short distance and long distance behaviour of G(x, y). It is...
متن کاملRelative Spectral Functions for Two Point Interactions in Three Dimensions
The regularized partition function at finite temperature for a massless scalar field interacting with two delta-like external potentials in R is evaluated in an explicit form making use of a rigorous approach based on the introduction of relative determinants associated with the presence of non compact manifold, as defined by Müller in [14], and on results of Albeverio et al. [1], dealing with ...
متن کاملFinite Volume Gauge Theory Partition Functions in Three Dimensions
We determine the fermion mass dependence of Euclidean finite volume partition functions for three-dimensional QCD in the ǫ-regime directly from the effective field theory of the pseudo-Goldstone modes by using zero-dimensional non-linear σ-models. New results are given for an arbitrary number of flavours in all three cases of complex, pseudo-real and real fermions, extending some previous consi...
متن کاملScaling functions for O(4) in three dimensions
Monte Carlo simulation using a cluster algorithm is used to compute the scaling part of the free energy for a three dimensional O(4) spin model. The results are relevant for analysis of lattice studies of high temperature QCD.
