Abstract:
In this paper, under the condition that $K$ is concave, we characterize lacunary series in $Q_{k}$ spaces. We improve a result due to H. Wulan and K. Zhu.

1. Fundamental theorem. In a recent paper f I have proved the theorem that if a lacunary trigonometric series CO (1) X(a* cos nk6 + bk sin nk9) (nk+x/nk > q > 1, 0 ^ 0 ^ 2ir) 4-1 has its partial sums uniformly bounded on a set of 0 of positive measure, then the series (2) ¿(a*2 + bk2) k-l converges. The proof was based on the following lemma (which was not stated explicitly but is contained in ...
full textA Note on Lacunary Lonely Runners
We give a simple argument proving the lonely runner conjecture in the case where the speed of the runners forms a certain lacunary sequence. This improves an earlier result by Pandey, and is then used to derive that for each number of runners the lonely runner conjecture is true for a set of nonzero measure in a natural probability space.
full textLacunary Series in Mixed Norm Spaces on the Ball and the Polydisk
We characterize lacunary series in mixed norm spaces on the unit ball B in C and on the unit polydisk D in C. Introduction and main results Let n be a positive integer. Two domains will be used in the paper: the open unit ball B in C, B = {z ∈ C : |z| < 1 }, and the open unit polydisk D in C, D = {z = (z1, ..., zn) ∈ C : |z1| < 1, ..., |zn| < 1 }. We write D = B = D. Denote by T the Shilov boun...
full textA note on soft topological spaces
This paper demonstrates the redundancies concerning the increasing popular ``soft set" approaches to general topologies. It is shown that there is a complement preserving isomorphism (preserving arbitrary $widetilde{bigcup}$ and arbitrary $widetilde{bigcap}$) between the lattice ($mathcal{ST}_E(X,E),widetilde{subset}$) of all soft sets on $X$ with the whole parameter set $E$ as domains and the ...
