M. Messager, j=E2=80=99ai trouv=C3=A9 quelque chose pour vous. https://dms.=
umontreal.ca/~mat6150/Notes_de_cours/Pages21a41deMat6150.pdf
Au =C2=A7 4.2 il est question de variables complexes.
"L=E2=80=99e=CC=81coulement plan peut aussi s=E2=80=99e=CC=81tudier avec la=
 variable complexe z =3D x + iy. Dans le plan complexe on de=CC=81finit alo=
rs un potentiel complexe w(x, y) par
w(x,y) =3D =CF=86(x,y)+i=CF=88(x,y). (92)"
Je vous remercie de m=E2=80=99avoir fait chercher, =C3=A7a me permettra de =
r=C3=A9viser aussi.
