Furthermore, the kinetic energy of u outside the cone is small. Consequently, depending on the sign of μ, we obtain two new types of solutions which either concentrate as t→∞ (with a continuum of rates) or stay bounded but do not scatter. In particular, these solutions contradict a strong version of the soliton resolution conjecture.text::journal::journal article::research article
