Title: Optimal error analysis of a non-uniform IMEX-L1 finite element method for time fractional PDEs and PIDEs

Authors: Aditi Tomar, Lok Pati Tripathi, Amiya K. Pani

Comments: In the revised version, we have consistently maintained the assumption that $u_0 \in H_0^1(\Omega)\cap H^2(\Omega)$, given the impracticality of assuming $u_0 \in \dot{H}^3(\Omega)$. It is important to highlight that all the derived estimates and bounds in this revised version remain valid as $\alpha\to 1^{-}$, where $\alpha$ denotes the order of the Caputo fractional derivative
