In the original page, there are two bibliographies and an empty comment section. Should there be just one bibliography? Remove comments section?--Juan José Torrens 01:59, 5 May 2012 (CEST)

Yes, bibs can be glued together. You may want to use this script to handle references, which does also get the entries into right order.
But see the warning there. --Ulf Rehmann 11:17, 5 May 2012 (CEST)


Should we use $D^{\alpha}_xf$ or $D^{\alpha}f$ instead of $f^{(k)}$ for derivatives? Because $f^{(k)}$ looks like $k$-th derivative of single variable function. Nikita2 (talk) 13:13, 23 November 2012 (CET)

(Please sign your comments.) Yes, that makes sense, in particular since this is the notation used on related pages like Generalized derivative.--Ulf Rehmann 10:36, 23 November 2012 (CET)
