Exotic smooth R4 and certain configurations of NS and D branes in string theory

4. Discussion and conclusions
In this paper we tried to give a partial answer to the important question: Is it possible
that string theory deals with 4-dimensional structures directly neither by im-plementing
compactifications nor by phenomenological models-building, and these structures would have a physical meaning?
