Local and global solutions for the non-linear Schrödinger-Boussinesq system. (English) Zbl 1224.35027

Summary: We study the local and global well posedness of the initial-value problem for the non-linear Schrödinger-Boussinesq system. Local existence results are proved for three initial data in Sobolev spaces of negative indices. Global results are proved using the arguments of J. Colliander, J. Holmer and N. Tzirakis [Trans. Am. Math. Soc. 360, No. 9, 4619–4638 (2008; Zbl 1158.35085)].
