Stability estimate for a partial data inverse problem for the convection-diffusion equation

<p style='text-indent:20px;'>In this article, we study the stability in inverse problem of determining time-dependent convection term and density coefficient appearing convection-diffusion equation, from partial boundary measurements. For dimension <inline-formula><tex-math id="M1">\begin{document}$ n\ge 2 $\end{document}</tex-math></inline-formula>, show (modulo gauge term) admits log-log stability, whereas log-log-log estimate is obtained for coefficient.</p>
