Turnpike and dissipativity properties in dynamic real-time optimization and economic MPC

Dominique Bonvin, Colin Neil Jones, Timm Faulwasser, Milan Korda

We investigate the turnpike and dissipativity properties of continuous-time optimal control problems. These properties play a key role in the analysis and design of schemes for dynamic real-time optimization and economic model predictive control. We show i ...

Effects of cosmic strings with delayed scaling on CMB anisotropy

Kohei Kamada

The network of cosmic strings generated in a phase transition during inflation enters the scaling regime later than that of usual strings. If it occurs after the recombination, temperature anisotropies of the cosmic microwave background (CMB) at high multi ...

Non-existence of multiple-black-hole solutions close to Kerr-Newman

Willie Wai Yeung Wong

We show that a stationary asymptotically flat electro-vacuum solution of Einstein's equations that is everywhere locally "almost isometric" to a Kerr-Newman solution cannot admit more than one event horizon. Axial symmetry is not assumed. In particular thi ...

Financial Supply Chain Management: Working Capital Requirements with Short-term Debt

Ralf Seifert, Margarita Protopappa, Cristopher Ariel Zeballos Avila

In this paper, we build on a single product, finite horizon, periodic review inventory management setting and include key financial aspects such as working capital constraints, payment delays and multiple sources of financing. We numerically solve for the ...

Modelling hybrid demand (e-commerce " plus " traditional) evolution: A scenario planning approach

Rémy Glardon, Naoufel Cheikhrouhou, Luca Canetta

This work presents a "3 steps-2 aggregation levels" methodological approach for modelling the evolution of the hybrid demand order flow pattern over long time horizons. The hybrid demand is the result of the mutual interaction between the e-commerce and th ...

Microlensing of the broad line region in 17 lensed quasars

Frédéric Courbin, Georges Meylan

When an image of a strongly lensed quasar is microlensed, the different components of its spectrum are expected to be differentially magnified owing to the different sizes of the corresponding emitting region. Chromatic changes are expected to be observed ...

A mean field approach for optimization in discrete time

Nicolas Gabriel Gast

This paper investigates the limit behavior of Markov decision processes made of independent objects evolving in a common environment, when the number of objects (N) goes to infinity. In the finite horizon case, we show that when the number of objects becom ...

Horava gravity versus thermodynamics: The black hole case

Sergey Sibiryakov, Diego Blas Temino

Under broad assumptions, breaking of Lorentz invariance in gravitational theories leads to tension with unitarity because it allows for processes that apparently violate the second law of thermodynamics. The crucial ingredient of this argument is the exist ...

A stochastic reach-avoid problem with random obstacles

Maryam Kamgarpour, John Lygeros

We present a dynamic programming based solution to a stochastic reachability problem for a controlled discrete-time stochastic hybrid system. A sum-multiplicative cost function is introduced along with a corresponding dynamic recursion which quantifies the ...
