[Existence, unicité et stabilité des équations différentielles stochastiques rétrogrades à coefficient localement monotone]
Nous prouvons l'existence, l'unicité et la stabilité des solutions d'équations différentielles stochastiques rétrogrades (EDSR), dont le coefficient vérifie une condition de type monotonie locale. Ces resultats sont obtenus avec un coefficient de croissance presque quadratique et une donnée terminale de carré intégrable. De plus le coefficient peut être ni localement Lipschitz en y ni en z.
We prove existence, uniqueness and stability of the solution for multidimensional backward stochastic differential equations (BSDE) with locally monotone coefficient. This is done with an almost quadratic growth coefficient and a square integrable terminal data. The coefficient could be neither locally Lipschitz in the variable y nor in the variable z.
