摘要：
This paper deals with the competitive power nonlinear Schrodinger equation, which originates from the cubic-quintic model in physics. The equation admits infinitely many excited solitons, and the Cauchy problem is globally well-posed in the energy space. In terms of Cote and Le Coz's argument, high-speed excited multi-solitons of the equation are constructed, which extend Cote and Le Coz's results from the focusing nonlinear cases to the competitive nonlinear cases combining the focusing nonlinearities and defocusing nonlinearities.
