Some sharp null-form type estimates for the Klein--Gordon equation
Jayson Cunanan, Shobu Shiraki
We establish a sharp bilinear estimate for the Klein--Gordon propagator in the spirit of recent work of Beltran--Vega. Our approach is inspired by work in the setting of the wave e…
Inhomogeneous Strichartz estimates in some critical cases
Neal Bez, Jayson Cunanan, Sanghyuk Lee
Strong-type inhomogeneous Strichartz estimates are shown to be false for the wave equation outside the so-called acceptable region. On a critical line where the acceptability condi…
Smoothing estimates for the kinetic transport equation at the critical regularity
Neal Bez, Jayson Cunanan, Sanghyuk Lee
We prove smoothing estimates for velocity averages of the kinetic transport equation in hyperbolic Sobolev spaces at the critical regularity, leading to a complete characterisation…
Asymptotic stability of the stationary Navier-Stokes flows in Besov spaces
Jayson Cunanan, Takahiro Okabe, Yohei Tsutsui
We discuss the asymptotic stability of stationary solutions to the incompressible Navier-Stokes equations on the whole space in Besov spaces with positive smoothness and low integr…
Trace operators on Wiener amalgam spaces
Jayson Cunanan, Yohei Tsutsui
The paper deals with trace operators of Wiener amalgam spaces using frequency-uniform decomposition operators and maximal inequalities, obtaining sharp results. Additionally, we pr…
On boundedness of pseudo-differential operators of Sjöstrand's class
Jayson Cunanan
We extended the known result that symbols from modulation spaces , also known as the Sjöstrand's class, produce bounded operators in $L^2(\mathbb{R}^…
