Global dynamics below the standing waves for the focusing semilinear Schrödinger equation with a repulsive Dirac delta potential
We consider the focusing mass-supercritical semilinear Schrödinger equation with a repulsive Dirac delta potential on the real line :ޒwhere Ä 0, ı 0 denotes the Dirac delta with the mass at the origin, and p > 5.By a result of Fukuizumi, Ohta, and Ozawa (2008), it is known that the …
