This thesis is devoted to the mathematical study of the swimming at low Reynolds number. The controllability and the optimal problems associated with the displacement of micro- swimmers are the main points developed in this work. In the first part, we study the controllability and the optimal control problem in time associated with a reduced model of swimmers, called the"N-link swimmer". In the second part, we study the boundary effect on the controllability of particular micro-swimmers made by several balls linked each others by thin jacks. Firstly, we analyze the effect of a plane wall on the mobility of these swimmers. Then, we generalize these results where the wall is rough. We demonstrate that a controllable swimmer remains controllab...
