Two kinds of numerical algorithms for ultra-slow diffusion equations
Min Cai, Changpin Li, Yu Wang
In this article, two kinds of numerical algorithms are derived for the ultra-slow (or superslow) diffusion equation in one and two space dimensions, where the ultra-slow diffusion…

Fractional SEIR Model and Data-Driven Predictions of COVID-19 Dynamics of Omicron Variant
Min Cai, George Em Karniadakis, Changpin Li
We study the dynamic evolution of COVID-19 cased by the Omicron variant via a fractional susceptible-exposedinfected-removed (SEIR) model. Preliminary data suggest that the symptom…

Fractional Buffer Layers: Absorbing Boundary Conditions for Wave Propagation
Min Cai, Ehsan Kharazmi, Changpin Li +1
We develop fractional buffer layers (FBLs) to absorb propagating waves without reflection in bounded domains. Our formulation is based on variable-order spatial fractional derivati…
