Distribution-valued weak solutions to a parabolic problem arising in financial mathematics

Michael Eydenberg, Maria Cristina Mariani

Abstract:
We study distribution-valued solutions to a parabolic problem that arises from a model of the Black-Scholes equation in option pricing. We give a minor generalization of known existence and uniqueness results for solutions in bounded domains $\Omega \subset \mathbb{R}^{n+1}$ to give existence of solutions for certain classes of distributions $f\in \mathcal{D}'(\Omega)$. We also study growth conditions for smooth solutions of certain parabolic equations on $\mathbb{R}^n\times (0,T)$ that have initial values in the space of distributions.
