Deformations of kink tails

We study the asymptotic properties of kinks in connection with deformation procedure. show that, upon field-theoretic model, asymptotics can change or remain unchanged, depending on deforming function. The cases both explicit and implicit are considered. In addition, we that procedure be applied to important case kinks. also prove for any kink a power-law tail, stability potential decreases as inverse square coordinate. physical consequences discussed: mass, well behavior kink-antikink force.
