On Lorentz-invariant 2D equations admitting long-lived localized solutions with a nontrivial structure

R. K. Salimov, T. R. Salimov, E. G. Ekomasov

The article studies Lorentz-invariant 2D equations with long-lived ($t\backsim 1000$ ) localized solutions. In the case of three scalar fields localized solutions with a nontrivia…
