In recent years there has been some research done on certain properties of the oscillation function --- see the references at the end of my answer to Oscillation of a Function. | |
| Dec 15, 2018 at 12:44 | comment | added | Dave L Renfro | This was essentially proved by Sierpinski in 1910 (reprinted on pp. 42-43 of Volume 2 of his Oeuvres Choisies), then generalized by Henry Blumberg 1 2 3 to cases in which the oscillation is computed by allowing for the neglect of countable, measure zero, and first category sets. Although the result appears in a few books (e.g. Hahn's 1921 treatise on real functions) and papers, (continued) | |
