One-Soliton Solutions

Obviously, the sine-Gordon equation has a trivial solution [Maple Math] . Substituting the trivial solution into the system "Backl_Trans", one obtains the one-soliton solutions Kink and Antikink.

Kink is the transition from one stationary solution, [Maple Math] , to another, [Maple Math] .

Antikink, in contrast to the kink, is the transition from the solution [Maple Math] to [Maple Math] .
