TY - GEN A1 - Ankirchner, Stefan A1 - Dereich, Steffen A1 - Imkeller, Peter T1 - Enlargement of filtrations and continuous Girsanov type embedding N2 - Let (Gt) be an enlargement of the filtration (Ft). Jeulin and Jacod discussed a sufficient criterion for the inheritance of the semimartingale property when passing to the larger filtration. We provide alternative proofs of their results in a more general setting by using decoupling measures and Girsanov's changes of measure. We derive necessary and sufficient conditions for the embedding of vector spaces of (Ft)-semimartingales into spaces of (Gt)-semimartingales to be continuous in terms of generalized entropies of the information increment.
