Higher-order ATM asymptotics for the CGMY model via the characteristic function
Allen Hoffmeyer, Christian Houdré
Using only the characteristic function, we derive short-time at-the-money (ATM) call-price asymptotics for the exponential CGMY model with activity parameter . The Lipto…

Derivatives Along a Curve and the Functional Stochastic Calculus
Christian Houdré, Jorge Víquez
Motivated by extending the functional stochastic calculus, to important functionals to which it does not apply, a notion of functional derivative along a curve is introduced. This…

A covariance representation and an elementary proof of the Gaussian concentration inequality
Christian Houdré
Via a covariance representation based on characteristic functions, a known elementary proof of the Gaussian concentration inequality is presented. A few other applications are brie…
