[https://doi.org/10.1016/0304-4149(91)90028-B]We consider the second order stochastic differential equation Xt + f(Xt, Xt) = Wt where t runs on the interval [0, 1], {Wt} is an ordinary Brownian motion and we impose the Dirichlet boundary conditions X(0) = a and X(l) = b. We show pathwise existence and uniqueness of a solution assuming sorne smoothness and monotonicity conditions on f, and we study the Markov property of the solution using an extended version of the Girsanov theorem dueto Kusuoka.25 p.application/pdfeng(c) David Nualart a et al., 1990Equacions diferencials estocàstiquesProcessos de MarkovUniversitat de Barcelona.
