| Abstract: |
| This paper is devoted to the Polynomial Preserving Recovery (PPR) based a posteriori error analysis for the second elliptic nonsymmetric eigenvalue problem. An asymptotically exact a posteriori error estimator is proposed for solving the convection-dominated nonsymmetric eigenvalue problem with non-smooth eigenfunctions or multiple eigenvalues. Numerical examples confirm our theoretical analysis. |
