Scattering below the ground state for the three-dimensional focusing energy-critical NLS

Qingtang Su, Zehua Zhao

We prove global well-posedness and scattering for the three-dimensional focusing energy-critical nonlinear Schrödinger equation with initial data below the ground-state energy and…

Full-radius dimension-free maximal inequalities for discrete Euclidean balls

Kaiwen Jin, Qingtang Su

For every $1 < p \leq \infty$ , we prove dimension-free maximal inequalities over all radii for normalized averages over Euclidean balls in $Z^{d}$ . In particular, this settles the…
