Abstract: | Solvability of linear forward-backward stochastic differential equations (FBSDEs, for short) with random coefficients is studied.
A decoupling reduction method is introduced via which a large class of linear FBSDEs with random or deterministic time-varying
coefficients is proved to be solvable. On the other hand, by means of Four Step Scheme, a Riccati backward stochastic equation
(BSDE, for short) for (m×n) matrix-valued processes is derived. Global solvability of such Riccati BSDEs is discussed for some special (but nontrivial)
cases, which leads to the solvability of the corresponding linear FBSDEs.
