The paper presents analysis of the G8 and G20 assistance to developing countries in overcoming the consequences of economic and financial crisis. It assesses the G8's and G20's implementation of key global governance functions and highlights their engagement with international organizations. In conclusion the author gives recommendations for rational division of labour between the institutions in international development assistance.
Writing the paper on the eve of the G20 summit in Cannes, the author expressed a view that except for French President Sarkozy, no one should be surprised by a disappointing outcome in Cannes. More importantly the author argues that this does not mean that the world economy will not be rebalanced just because the G-20 did not ordain the solution. Unsustainable imbalances will eventually be adjusted by economic forces. Refraining from meaningful and urgent collective action, the G-20 leaders choose to let the world rebalance itself more chaotically, with the inevitable result of making things harder for each other. This is not a collective leadership but a joint abdication of responsibility. To prove its usefulness, the G-20 must do more than help old and emerging economic powers agree to disagree. The paper asserts that if the G20 fails the test, it is only a matter of time when the new creditors will see it as in their individual interests to make common cause either to reform existing institutions or to create new ones free of the dominance of the debtor countries. The author concludes that we can only hope that a new grouping of major creditors arrives as the successor to the G-20 in time to avert a replay of the 1930s.

We consider certain spaces of functions on the circle, which naturally appear in harmonic analysis, and superposition operators on these spaces. We study the following question: which functions have the property that each their superposition with a homeomorphism of the circle belongs to a given space? We also study the multidimensional case.
We consider the spaces of functions on the m-dimensional torus, whose Fourier transform is p -summable. We obtain estimates for the norms of the exponential functions deformed by a C1 -smooth phase. The results generalize to the multidimensional case the one-dimensional results obtained by the author earlier in “Quantitative estimates in the Beurling—Helson theorem”, Sbornik: Mathematics, 201:12 (2010), 1811 – 1836.
