报告摘要:We consider the Cauchy problem to the 3D fractional Schrödinger equation with quadratic interaction of uū type. We prove the global existence of solutions and scattering properties for small initial data. For the proof, one novelty is that we combine the normal form methods and the space-time resonance methods. Using the normal form transform enables us more flexibilities in designing the resolution spaces so that we can control various interactions. It is also convenient for the final data problem. This is a joint work with Naijia Liu and Liang Song.
