Generalized Stochastic Resilience for Early Warning Signals Based on Koopman Operator

Yuta Miyauchi, Masahiro Ikeda, Yoshinobu Kawahara

Developing methods for detecting tipping phenomena at an early stage is an important problem in various fields such as ecology, medicine, and economics. A tipping phenomenon is cha…

Critical curve for the weakly coupled system of damped wave equations with mixed nonlinearities

Dinh Van Duong, Tuan Anh Dao, Masahiro Ikeda

In this paper, we would like to consider the Cauchy problem for a weakly coupled system of semi-linear damped wave equations with mixed nonlinear terms. Our main objective is to dr…

Asymptotically self-similar global solutions for Hardy-Hénon parabolic equations

Noboru Chikami, Masahiro Ikeda, Koichi Taniguchi +1

We construct asymptotically self-similar global solutions to the Hardy-Hénon parabolic equation $\partial_{t} u - Δ u = \pm ∣ x ∣^{γ} ∣ u ∣^{α - 1} u$ , $α > 1$ , $γ \in R$ for a large cl…

Optimal $L^{2}$ -blowup estimates of the Fractional Wave Equation

Masahiro Ikeda, Jinhong Zhao

This article deals with the behavior in time of the solution to the Cauchy problem for a fractional wave equation with a weighted $L^{1}$ initial data. Initially, we establish the gl…
