Optimal constants of smoothing estimates for the 3D Dirac equation
Makoto Ikoma, Soichiro Suzuki
Recently, Ikoma (2022) considered optimal constants and extremisers for the -dimensional Dirac equation using the spherical harmonics decomposition. Though its argument is valid…

Optimal constants of smoothing estimates for Dirac equations with radial data
Makoto Ikoma, Soichiro Suzuki
Kato--Yajima smoothing estimates are one of the fundamental results in study of dispersive equations such as Schrödinger equations and Dirac equations. For -dimensional Schröd…
