## Global existence of small solutions to semilinear Schrödinger equations.(English)Zbl 0843.35111

Summary: We present global existence theorem for semilinear Schrödinger equations. In general, Schrödinger-type equations do not admit the classical energy estimates. To avoid this difficulty, we use S. Doi’s method for linear Schrödinger-type equations. Combining his method and $$L^p- L^q$$ estimates, we prove the global existence of solutions with small initial data.
