Gauge-reversing maps on cones, and Hilbert and Thompson isometries
Cormac Walsh
We show that a cone admits a gauge-reversing map if and only if it is a symmetric cone. We use this to prove that every isometry of a Hilbert geometry is a collineation unless the…
Random walk with heavy tail and negative drift conditioned by its minimum and final values
Vincent Bansaye, Vladimir Vatutin
We consider random walks with finite second moment which drifts to and have heavy tail. We focus on the events when the minimum and the final value of this walk belong to…
Accelerated Share Repurchase: pricing and execution strategy
Olivier Guéant, Jiang Pu, Guillaume Royer
In this article, we consider the optimal execution problem associated to accelerated share repurchase contracts. When firms want to repurchase their own shares, they often enter su…
Liquidation of an indivisible asset with independent investment
Emilie Fabre, Guillaume Royer, Nizar Touzi
We provide an extension of the explicit solution of a mixed optimal stopping-optimal stochastic control problem introduced by Henderson and Hobson. The problem examines wether the…
Interface motion in random media
Thierry Bodineau, Augusto Teixeira
We study the pinning phase transition for discrete surface dynamics in random environments. A renormalization procedure is devised to prove that the interface moves with positive v…
Nash equilibrium for coupling of CO2 allowances and electricity markets
Mireille Bossy, Nadia Maizi, Odile Pourtallier
In this note, we present an existence result of a Nash equilibrium between electricity producers selling their production on an electricity market and buying CO2 emission allowance…
