Inverse problem for time-series valued computer model via scalarization
Pritam Ranjan, Mark Thomas, Holger Teismann +1
For an expensive to evaluate computer simulator, even the estimate of the overall surface can be a challenging problem. In this paper, we focus on the estimation of the inverse sol…
Would Real Analysis be complete without the Fundamental Theorem of Calculus?
Michael Deveau, Holger Teismann
The paper continues the intriguing theme that many key facts of (single-variable) Real Analysis are not only crucially dependent on the completeness of the real numbers, but are ac…
Minimal time for the bilinear control of Schrödinger equations
Karine Beauchard, Jean-Michel Coron, Holger Teismann
We consider a quantum particle in a potential V (x) (x in R^N) subject to a (spatially homogeneous) time-dependent electric field E(t), which plays the role of the control. Under g…
Rigorous numerics for NLS: bound states, spectra, and controllability
Roberto Castelli, Holger Teismann
In this paper it is demonstrated how rigorous numerics may be applied to the one-dimensional nonlinear Schrödinger equation (NLS); specifically, to determining bound--state solutio…
The modellers' encounter with ecological theory. Or, what is this thing called `growth rate'?
Michael Deveau, Richard Karsten, Holger Teismann
The attempt to determine the population growth rate from field data reveals several ambiguities in its definition(s), which seem to throw into question the very concept itself. How…
Local exact controllability of a 1D Bose-Einstein condensate in a time-varying box
Karine Beauchard, Horst Lange, Holger Teismann
We consider a one-dimensional Bose-Einstein condensate in a infinite square-well (box) potential. This is a nonlinear control system in which the state is the wave function of the…
