On the Cauchy problem of fractional Schrödinger equation with Hartree type nonlinearity

Yonggeun Cho, Gyeongha Hwang, Hichem Hajaiej +1

We study the Cauchy problem for the fractional Schrödinger equation $i \partial_{t} u = (m^{2} - Δ)^{\frac{α}{2}} u + F (u) in R^{1 + n},$ where $n \geq 1$ , $m \geq 0$ , $1 < α < 2$ ,…

Profile decompositions and Blowup phenomena of mass critical fractional Schrödinger equations

Yonggeun Cho, Gyeongha Hwang, Soonsik Kwon +1

We study, under the radial symmetry assumption, the solutions to the fractional Schrödinger equations of critical nonlinearity in $R^{1 + d}, d \geq 2$ , with Lévy index ${2d}…

On finite time blowup for mass-critical Hartree equations

Yonggeun Cho, Gyeongha Hwang, Soonsik Kwon +1

We consider the fractional Schrödinger equations with focusing Hartree type nonlinearity. When the energy is negative, we use a Glassey's virial type argument to show the finite ti…
