Buvoli's conjecture. As the approximation order tends to infinity, the absolute stability regions should tend to

Let $W$ be the admissible parameter region for the multistep family, let $\mathcal{S}_{\beta_1,\beta_0}$ be the corresponding stability region, and let … The parameter $m$ is admis…

Let $P_{\beta_1,\beta_0}$ and $\mathcal{S}_{\beta_1,\beta_0}$ denote the stability polynomial and stability region associated with parameters $(\beta_1,\beta_0)$, and let … For a s…

Stiff stability conjecture. If the EAB$_k$ scheme is $A(\alpha)$-stable for $\theta$, then it is also stiff stable.
