Do the Euler equations (where I1,I2,I3 are principal moments of inertia):
I1˙ω1+(I3−I2)ω2ω3=M1
I2˙ω2+(I1−I3)ω3ω1=M2
I3˙ω3+(I2−I1)ω1ω2=M3
in their above general form have a Lagrangian? If not, does a specific case of ω1=ω2=0 (and so M1=M2=0) have a general Lagrangian? (M3 is the torque coming from a central gravitational potential - a planet - keeping the body (a satellite) on an elliptic orbit.)
