內容介紹:In this talk, we discuss an efficient parameter recovery reduced-order method for the Allen-Cahn equation. The reduced basis is constructed based on proper orthogonal decomposition and parametrized solution snapshots. Numerical analysis of the proposed method is conducted to derive error estimates for the reduced-order solutions. The impact on the accuracy of time difference quotients as snapshots is also investigated.
