Modified wave operators for the defocusing cubic nonlinear Schrödinger equation in one space dimension with large scattering data

Masaki Kawamoto, Haruya Mizutani

In the present paper, we construct modified wave operators for the defocusing cubic nonlinear Schrödinger equation (NLS) in one space dimension without size restriction on scatter…

Modified scattering for nonlinear Schrödinger equations with long-range potentials

Masaki Kawamoto, Haruya Mizutani

We study the final state problem for the nonlinear Schrödinger equation with a critical long-range nonlinearity and a long-range linear potential. Given a prescribed asymptotic pr…

Global Kato smoothing and Strichartz estimates for higher-order Schrödinger operators with rough decay potentials

Haruya Mizutani, Xiaohua Yao

Let \( H = (-Δ)^m + V \) be a higher-order elliptic operator on \( L^2(\mathbb{R}^n) \), where \( V \) is a general bounded decaying potential. This paper focuses on the global Ka…

Limiting absorption principle and absence of eigenvalues for massless Klein-Gordon operators on perturbations of the Minkowski spacetime

Haruya Mizutani

We prove a uniform weighted resolvent estimate for the massless Klein-Gordon operator on a curved spacetime which is sufficiently close to the Minkowski spacetime. This particularl…
