Stiff Norm Estimates for Variable-Stepsize Peer Two-Step Methods
Jens Lang, Bernhard A. Schmitt
Peer two-step methods are attractive for the numerical solution of stiff initial value problems because they combine favorable features of Runge-Kutta and multi-step methods, inclu…

Implicit Third-Order Peer Triplets with Variable Stepsizes for Gradient-Based Solutions in Large-Scale ODE-Constrained Optimal Control
Jens Lang, Bernhard A. Schmitt
This paper is concerned with the theory, construction and application of variable-stepsize implicit Peer two-step methods that are super-convergent for variable stepsizes, i.e., pr…

Variable-Stepsize Implicit Peer Triplets in ODE Constrained Optimal Control
Jens Lang, Bernhard A. Schmitt
This paper is concerned with the theory, construction and application of implicit Peer two-step methods that are super-convergent for variable stepsizes, i.e., preserve their class…
