Logarithmic stability for determining the damping coefficient for the time-fractional damped wave equation
Kai Yu, Zhiyuan Li
This paper investigates the inverse problem of determining the spatially dependent damping coefficient in a time-fractional damped wave equation, where the damping term is given by…
Uniqueness for an inverse coefficient problem of a weakly coupled parabolic system
Caixuan Ren, Kai Yu, Zhiyuan Li
This paper considers the weakly coupled parabolic system with the homogeneous Neumann boundary condition, where \(P(x)\) is a \(2\times2\) sym…
Hölder Stable Recovery of the Source in Space-Time Fractional Wave Equations
Kuang Huang, Zhiyuan Li, Zhidong Zhang +1
We study the recovery of a spatially dependent source in a one-dimensional space-time fractional wave equation using boundary measurement data collected at a single endpoint. The m…
Sharp decay estimates and numerical analysis for weakly coupled systems of two subdiffusion equations
Zhiyuan Li, Yikan Liu, Kazuma Wada
This paper investigates the initial-boundary value problem for weakly coupled systems of time-fractional subdiffusion equations with spatially and temporally varying coupling coeff…
