RésuméIn this paper, we detail some results of a previous note concerning a trigonometric expansion of the Weierstrass elliptic function . In particular, this implies its classical Fourier expansion. We use a direct integration method of the ODEwhere P(u) is a polynomial of degree n = 2 or 3. In this case, the bifurcations of (E) depend on one parameter only. Moreover, this global method seems not to apply to the cases n > 3.
