In this paper, topological approach are used for searching and stability analysis of relative equilibriums for the system of three point vortices of equal in magnitude intensities. It is shown that the system of three point vortices can be reduced by one degree of freedom. We find the two new stationary configurations (isosceles and non-symmetrical collinear), study their bifurcations. The stability analysis is performed for these cases.
Mots-clés : point vortex, equations of motion
Keywords: reduction, bifurcational diagram, relative equilibriums.
