Abstract
A rotation number is defined for fairly general diffeomorphisms in 2 dimensions and flows in 3 dimensions. An extension to higher dimensionality is sometimes also possible (in particular for Hamiltonian flows) On definit un nombre de rotation pour des diffeomorphismes a 2 dimensions et des flots a trois dimensions assez generaux. Une extension a des dimensions superieures est egalement possible dans certains cas (en particulier pour des flots hamiltoniens)
