Strichartz estimates for quasi-periodic functions on long time intervals: An arithmetic approach
Kotaro Inami
We study long-time Strichartz estimates for the one-dimensional Schrödinger equation with quasi-periodic initial data. For two-frequency data with an algebraic frequency ratio, we…

Equivalence between the energy decay of fractional damped Klein-Gordon equations and geometric conditions for damping coefficients
Kotaro Inami, Soichiro Suzuki
We consider damped -fractional Klein--Gordon equations on , where denotes the order of the fractional Laplacian. In the one-dimensional case , Green (20…
