WebHeston model (when n goes to infinity). We show that the lifted model enjoys the best of both worlds: Markovianity and satisfactory fits of implied volatility smiles for short maturities with very few parameters. Further, our approach speeds up the calibration time and opens the door to time-efficient simulation schemes. PDF http://www.homepages.ucl.ac.uk/~ucahwts/lgsnotes/Heston09.pdf
