Some remarks on the Cauchy Problem for Schrödinger type equations in Gelfand–Shilov spaces
摘要
We consider the Cauchy problem for Schrödinger type operators. Under a suitable decay assumption on the imaginary part of the first order coefficients we prove well-posedness of the Cauchy problem in Gelfand–Shilov classes. We also discuss the optimality of our result through some examples.
