# Talk:Lacunary sequence

Post $\TeX$ notes

• I replace the sequence notation $\{\cdot\}$ by the more usual $(\cdot)$, uncomment the \newcommand for \seq at the start of the file to revert this
• I'm not entirely sure about the MSC here, could someone check it?

About MSC: problematic indeed; but I believe that 42A55 "Lacunary series of trigonometric and other functions; Riesz products" is naturally the secondary classification, since it gives the main motivation here.
And maybe 11B05 "Density, gaps, topology" rather than just 11Bxx? Indeed, lacunary sequences are somehow of very small density, with many large gaps. --Boris Tsirelson 22:31, 3 May 2012 (CEST)
Agreed, thanks Boris --Jjg 23:41, 3 May 2012 (CEST)
