sine-Gordon equation (1.1) is by definition a stationary (τ-independent) solution used to locate non-imaginary points of σ(P) corresponding to instability.

In general, the input to the sine function can be positive, negative, fractional, or even irrational. However, a fixed-point sine function should (most likely) accept a fixed-point angle as an input. the two-dimensional sine-Gordon model possesses a nontrivial UV fixed point which makes the model asymptoticallysafe.Thefixedpointexhibitsstrongsingularitysimilartothescalingfoundinthevicinityof theinfraredfixedpoint.Thesingularitysignalstheupperenergy-scalelimittothevalidityofthemodel.We SINE-GORDON EQUATIONS BASED ON THE FIXED POINT THEORY OZGUR YILDIRIM AND MELTEM UZUN In the present work the numerical solution and unique solvability of coupled sine Gordon equations is considered.

The beta functions have a zero which is a bifurcation point that divides the parameter space into two regions; they are the weak-coupling region and the strong-coupling region. A large-N model is also considered. This model is reduced to the conventional sine-Gordon model that describes the Kosterlitz-Thouless transition near the fixed point.

In d = 2, using Wegner-Houghton RG we demonstrate that the location of the phase boundary is entirely driven by the relative position to the Coleman fixed point even for strongly coupled bare theories. 2016-02-01 In the framework of the functional renormalization group method it is shown that the phase structure of the 2-dimensional sine-Gordon model possesses a nontrivial UV fixed point which makes the XXZ/Sine-Gordon equivalence, paramter correspondance; Luther point in XXZ?

This model is reduced to the conventional sine-Gordon model that describes the Kosterlitz-Thouless transition near the fixed point.
