On concentration of positive bound states of nonlinear Schrödinger equations. (English) Zbl 0795.35118
The author studies the concentration behavior of positive bound states of the nonlinear Schrödinger equation with power law nonlinearity. The most interesting result is that positive radial solutions with least energy concentrate at the origin as the coefficient of $$\Delta\psi$$ tends to zero.
