A posteriori error estimates for the two-step explicit exponential Adams method for parabolic equations
Xianfa Hu, Wansheng Wang
In this paper, we derive optimal order a posteriori error estimates for the variable step-size explicit two-step exponential Adams (E-Adams2) method for parabolic problems. We begi…

A posteriori error estimates for the exponential midpoint method for linear and semilinear parabolic equations
Xianfa Hu, Wansheng Wang, Mengli Mao +1
In this paper, the a posteriori error estimates of the exponential midpoint method for time discretization are studied for linear and semilinear parabolic equations. Using the expo…
