First-passage and risk evaluation under stochastic volatility
Jaume Masoliver, Josep Perello
We solve the first-passage problem for the Heston random diffusion model. We obtain exact analytical expressions for the survival and hitting probabilities to a given level of retu…

The escape problem under stochastic volatility: the Heston model
Jaume Masoliver, Josep Perello
We solve the escape problem for the Heston random diffusion model. We obtain exact expressions for the survival probability (which ammounts to solving the complete escape problem)…
