A Hamilton-Jacobi Approach to Time-Delayed Nonlocal Diffusion Models in Shifting Habitats
Bing-Er Jiang, King-Yeung Lam, Wan-Tong Li +1
The paper analyzes how populations spread in shifting environments using time‑delayed nonlocal diffusion equations, applying viscosity solutions of Hamilton‑Jacobi equations to cla…

Propagation dynamics for nonlocal dispersal predator-prey systems in shifting habitats: A Hamilton-Jacobi approach
Wen Tao, Wan-Tong Li, Shigui Ruan +1
This paper is concerned with the spreading speeds of nonlocal dispersal predator-prey systems in shifting habitats under general initial conditions. By employing geometric optics t…

First Passage Times for Variable-Order Time-Fractional Diffusion
Wancheng Li, Daniel S. Han
We derive the asymptotic first passage time (FPT) distribution for space-dependent variable-order time-fractional diffusion, where the fractional exponent varies with posit…
