Generalized Fubini instanton | A.A. Yurova

17 Sep 2007 | Abstract: | We show that $(1+2)$ nonlinear Klein-Gordon equation with negative coupling
admits an exact solution which appears to be the linear superposition of the
plane wave and the nonsingular rational soliton. We show that the same approach
allows to construct the solution of similar properties for the Euclidean
$phi^4$ model with broken symmetry. Interestingly, this regular solution will
be of instanton type only in the $Dle 5$ Euclidean space. | Source: | arXiv, 0709.2546 | Services: | Forum | Review | PDF | Favorites |
