→Running career: There are two meanings of "football" (as a sport) in UK-English (=soccer) and US-English (American football). An encyclopedia is for reading, not necessarily for clicking, and for clarity for, e.g., US readers "soccer" should be visually present at this point. It also doesn't hurt and is correct.

talk) The oringinal contribution by Petergans deserves to stay as just an opinion. Prof Lazard acts "as usual". I acknowledge that his opinions mostly have merits as in this case. His actions, I find not.Tags: UndoReverted

Schrödinger equation

MichaelMaggs (
talk) The previous short description was better (more professional. The S-Eq is a LPDEq. The vague "Equation" can be misleading in that it is not as simple as eg. a quadratic equation. Quantum Mechanics is the physics subfield. So quantum mechanical system is more appropriate.Tag: Undo

Lp space
→Hilbert spaces: Upgraded the formulation: vector spaces are usually called isometrically isomorphic in this context, since one has a linear isomorphism which is isometric. The set E in the l2(E) claim is literally the chosen maximally orthonormal subset.

Bra–ket notation
V needs to be complete in order to be a Hilbert space which is nowhere mentioned where I replaced H-space with inner product space. The latter is all that's needed for bra/ket discussion at this point.

Least-upper-bound property
→Heine–Borel theorem: Corrected tiny mistake in the previous nice presentation, in that it was not mentioned early enough that the construction with \delta can only proceed, if c<b. Text made a bit more detailed, logical and formally tailored to the application of LUB-ax.
