Z|2 We obtain (10c). Another way to obtain (10c) uses the symmetry of interchanging the variables, a unitary change in the domain. Consider the map (z, w) → (z 2 , w) = h(z, w). On the sphere, we have |z|4 + |w|2 = ||h(z, w)||2 = ||h(w, z)||2 = |w|4 + |z|2 . (13) Dividing both sides of (13) by |z|2 and moving the | wz |2 term over yields (10c). We could have divided instead by |w|2 and found an equivalent map. More interesting is to divide by |z|4 . Then we obtain the map 2 1 2 w , z, w z2 from Lebl’s list [21], which (by [25]) is also equivalent to (10c).

12 Let C be an annulus of R2N included in the set ξ ∈ R2N / |ξ| > 1 . For any nonnegative integer k, there exist positive constants Ck and Ck so that, for any real number p ≥ 1 and any function u belonging to L p (R2N ) satisfying Supp u ⊂ eλ C , with λ ≥ 1, we have C k λk u L p (R2N ) ≤ (log |D|)k u L p (R2N ) ≤ C k λk u L p (R2N ) . 8 is more challenging. The result we obtain in the logarithmic frame reads differently from that of the classical case, but expresses the same phenomenon, namely that we lose 2N 1p − q1 derivatives in the passage from the L p norm to the L q norm, for q ≥ p ≥ 1.
