Dilemmas of Internationalism

"Dilemmas of Internationalism" is a brand new political historical past of the Forties which charts and analyses the efforts of personal internationalists to outline US internationalism and advertise the institution of the United countries. Internationalists was hoping that the us could shake off the phobia of entangling alliances that had characterized the nation's background, exchanging isolationism and unilateralism with a brand new, concerned and multilateral method of overseas affairs.

5) α,β∈Zn + |α|+|β|≤N Clearly ε,δ ε,δ [v] = sup SN [v] = v lim SN N →∞ N ∈Z+ ε,δ . 6) As F (u) is polynomial, we may assume without loss of generality that F (u) = uk for some k ∈ Z+ , k ≥ 2. 7) is continuous for all µ, ν ∈ Zn+ , |µ| ≤ 2, |ν| ≤ 2. 8) 56 M. Cappiello, T. Gramchev and L. Rodino Next, we show identities for commutators. 9) 1≤|µ|+|ν|≤3 for all α, β ∈ Zn+ , |α| + |β| > 0. 11) for all ρ, σ ∈ Z+ . 9). Similar identities can be found for the commutators [xβ ∂xα , ∆] and [xβ ∂xα , |x|2 ].

We shall limit ourselves here to recall from [6, 7, 15, 19] the following a priori estimate for L2 -norms, which we shall use later: if P is globally elliptic of order m, then there exists a positive constant C such that for all u ∈ S(Rn ) xα Dβ u ≤ C ( P u + u ) . 3) |α|≤m |β|≤m We introduce a subclass of S11 (Rn ). 1. We denote by S11 (Rn ) the class of all functions f ∈ S(Rn ) such that, for every N ∈ Z+ and for some constant C > 0 independent of N xα Dβ f ≤ C N +1 N N for every (α, β) ∈ MN .
