Almost Sure Exponential Stability of Neutral Differential Difference Equations. . .

open access: yes, 1996
: In this paper we shall discuss the almost sure exponential stability for a neutral differential difference equation with damped stochastic perturbations of the form d[x(t) \Gamma G(x(t \Gamma ø ))] = f(t; x(t); x(t \Gamma ø ))dt + oe(t)dw(t): Several ...

Optimal stopping in Hilbert spaces and pricing of American options

open access: yes, 2007
We consider an optimal stopping problem for a Hilbert-space valued diffusion. We prove that the value function of the problem is the unique viscosity solution of an obstacle problem for the associated parabolic partial differential equation in the ...

Asset price bubbles from heterogeneous beliefs about mean reversion rates

open access: yes
Harrison and Kreps showed in 1978 how the heterogeneity of investor beliefs can drive speculation, leading the price of an asset to exceed its intrinsic value.

Constructing quantum measurement processes via classical stochastic calculus

open access: yes
A class of linear stochastic differential equations in Hilbert spaces is studied, which allows to construct probability densities and to generate changes in the probability measure one started with.
