Abstract

The global existence and regularity problem on the Oldroyd‑B‑type model with fractional dissipation is not well understood for many ranges of fractional powers. This paper examines this open problem from a different perspective. We construct a class of large solutions to the $d$‑dimensional $(d=2,3)$ Oldroyd‑B‑type models with the fractional dissipation $(-\Delta)^\alpha u$ and $(-\Delta)^\beta \tau$ when the fractional powers satisfy $\alpha + \beta \geq 1$. The process presented here actually assesses that an initial data near any function whose Fourier transform lives in a compact set away from the origin always leads to a unique and global solution.
