The affine Artin group of type is virtually poly-free
Li Li, S. K. Roushon
In this note we prove that the affine Artin group of type is virtually poly-free. The proof also gives another solution of the problem for $\widetilde B…

An inverse problem for the fractional Allen-Cahn equation
Li Li
We study an inverse problem for the fractional Allen-Cahn equation. Our formulation and arguments rely on the asymptotics for the fractional equation and unique continuation proper…

An inverse problem for the space-time fractional Schrödinger equation on closed manifolds
Li Li
We formulate an inverse problem for an uncoupled space-time fractional Schrödinger equation on closed manifolds. Our main goal is to determine the fractional powers and the Rieman…
