Nikolaos Pattakos

摘要:

在调制空间$M_{2,q}^{s}(\mathbb R)$,$1\leq q\leq2$和$s\geq0.$中证明了三次非线性Schr dinger方程广义Cauchy问题弱解的存在性。对于$s\geq 0$和$1\leq q\leq\frac32$或$\frac32<q\leq 2$和$s>\frac23-\frac1{q}$,我们证明了Cauchy问题在$M_{2,q}^{s}(\mathbb R).$中是无条件适定的。设置.

英文摘要:

We show the existence of weak solutions in the extended sense of the Cauchy problem for the cubic nonlinear Schrödinger equation in the modulation space $M_{2,q}^{s}(\mathbb R)$, $1\leq q\leq2$ and $s\geq0.$ In addition, for either $s\geq 0$ and $1\leq q\leq\frac32$ or $\frac32<q\leq 2$ and $s>\frac23-\frac1{q}$ we show that the Cauchy problem is unconditionally wellposed in $M_{2,q}^{s}(\mathbb R).$ It is done with the use of the differentiation by parts technique which had been previously used in the periodic setting.
