ABSTRACT
We show that the sharp constant in the classical n-dimensional Hardyâ€“Leray inequality can be improved for axisymmetric divergence-free fields, and find its optimal value. The same result is obtained for n = 2 without the axisymmetry assumption.

For a given strictly decreasing sequence $\ a_n\^\infty_\left\{n=0\right\}$ of real numbers convergent to zero, we construct a continuous function $g$ on the closed interval $\left[-1,1\right]$ such that $R_\left\{2n\right\}\left(g\right)$ and $a_n$ have identical order of decrease as...

Let R be a prime ring with characteristic different from 2, let U be a nonzero Lie ideal of R, and let f be a generalized derivation associated with d. We prove the following results: (i) If a âˆŠ R and [a, f(U)] = 0 then a âˆŠ Z or d(a) = 0 or U âŠ‚ Z; (ii) If fÂ²(U) = 0 then U...

Using almost-invariant sets, we show that a family of Marczewski-Burstin algebras over groups are not closed under algebraic sums. We also give an application of almost-invariant sets to the difference property in the sense of de Bruijn. In particular, we show that if G is a perfect Abelian...
