Path properties and regularity of affine processes on general state spaces
affine processes path properties regularity Markov semimartingales
2011/7/20
We provide a new proof for regularity of affine processes on general state spaces by methods from the theory of Markovian semimartingales. On the way to this result we also show that the definition of...
Risk Sensitive Investment Management with Affine Processes: a Viscosity Approach
Asset management risk-sensitive stochastic control jump diffusion processes
2010/10/19
In this paper, we extend the jump-diffusion model proposed by Davis and Lleo to include jumps in asset prices as well as valuation factors. The criterion, following earlier work by Bielecki, Pliska, ...

The article provides the mathematical foundation for stochastically continuous affine processes on the cone of positive semidefinite symmetric matrices. This analysis has been motivated by a large and...
