On démontre l'existence, la régularité et une formule de représentation de Feynman–Kač de la solution forte d'un problème avec frontière libre. Ce type de problème on le retrouve en finance pour évaluer le prix d'une option asiatique à moyenne arithmétique de style américain.
We prove existence, regularity and a Feynman–Kač representation formula of the strong solution to the free boundary problem arising in the financial problem of the pricing of the American Asian option with arithmetic average.
