But opportunities for a more positive relationship between the city and its periphery do exist and should be urgently addressed at Rio+20 and beyond,” Marshall and Mehta conclude.

It is proved that the operators σ n of the triangular-Fejérmeans of a two-dimensional Walsh–Fourier series are uniformly bounded from the dyadic Hardy space Hp to Lp for all 4/5 < p ≤ ∞.

People mostly see poverty and marginal labour market status as indicators of laziness and own tax evasion behaviour. People believe that the actual income of the poor and of people with disadvantageous labour market status is considerably more than that they declare. Analo...

2 00 9 k - fold sums from a set with few products Dedicated to the memory of György Elekes

Before we state our main theorems, we begin with some notation: given a finite subset A of some commutative ring, we let A + A denote the set of sums a + b, where a, b ∈ A; and, we let A.A denote the set of products ab, a, b ∈ A. When three or more sums or products are used, we let kA denote the k-fold sumset A+A+ · · ·+A, and let A denote the k-fold product set A.A...A. Lastly, by d ∗ A we mea...
