Immersion Property and Credit Risk Modelling,known that such a construction rises mathematical difficulties, mainly relied to the properties of the random time. Whereas the invariance of the property of semi-martingale in the enlargement is implied by the absence of arbitrage, we address in this paper the question of the invariance of the martingale property.

For a finite time horizon, the problem gets considerably more complicated and cannot be solved explicitly. In this paper we study generic properties of the optimal stopping set and its boundary curve, and derive an integral equation for the latter.

,Long Time Growth Optimal Portfolio with Transaction Costs,ns of capital invested in assets to be ergodic. Existence of solutions to suitable Bellman equations is proved and the form of optimal strategies is shown. For continuous time model an additional fixed deterministic delay in transactions is assumed.
