Let F be a field of characteristic p> 0. Let Ω n (F) be the F-vector space of n-differentials of F over F p. Let K= F (g) be the function field of an irreducible polynomial g in m⩾ 1 variables over F. We derive an explicit description of the kernel of the restriction map Ω n (F)→ Ω n (K). As an application in the case p= 2, we determine the kernel of the restriction map when passing from the Witt ring (resp. graded Witt ring) of symmetric bilinear forms over F to that over such a function field extension K.
