H. Brezis and L. Nirenberg proved that if (g k ) ⊂ C 0 (S N , S N ) and g ∈ C 0 (S N , S N ) (N ≥ 1) are such that g k → g in BMO(S N ), then deg g k → deg g. On the other hand, if g ∈ C 1 (S N , S N ), then Kronecker's formula asserts that deg g = 1 In the same spirit, we consider the quantity J(g, ψ) := S N ψ det(∇g) dσ, for all ψ ∈ C 1 (S N , R) and study the convergence of J(g k , ψ). In particular, we prove that J(g k , ψ) converges to J(g, ψ) for any ψ ∈ C 1 (S N , R) if g k converges to
