- 13:2613:26, 1 June 2022 diff hist +65 m Resolvent (Galois theory) →Definition: cleared up tiny omissions/grammar
25 May 2022
- 08:4708:47, 25 May 2022 diff hist +1,215 Group cohomology →Low-dimensional cohomology groups: This is a very good section; but for readers unfamiliar with the manipulations of these maps it was a little terse in my opinion.
22 February 2022
- 08:1008:10, 22 February 2022 diff hist +407 Inverse trigonometric functions →Notation: I have pointed out the danger of this "convention" : it is predicated on handwriting styles ..... and no serious research-level mathematical reference text has ever used it, to my knowledge.
- 07:2607:26, 22 February 2022 diff hist +11 m Inverse trigonometric functions →Principal values: small grammar correction and added link to what countably infinite means
20 January 2022
- 09:4509:45, 20 January 2022 diff hist +4 m Abc conjecture →Refined forms, generalizations and related statements: grammar
- 09:3009:30, 20 January 2022 diff hist +12 m Abc conjecture →Claimed proofs: grammar
- 09:2409:24, 20 January 2022 diff hist +1 m Abc conjecture →Refined forms, generalizations and related statements: "incited" implies aggression or violence!!
- 08:2008:20, 20 January 2022 diff hist +67 m Mason–Stothers theorem →Examples: just clarified a pedantic but important point!
28 December 2021
- 09:2709:27, 28 December 2021 diff hist +51 m Separable state →Separability criterion: NP-hardness has not been shown in general; only in a large class of cases
13 October 2021
- 15:5315:53, 13 October 2021 diff hist +92 m Hilbert's Theorem 90 →Cohomology: made notation more consistent further down
9 October 2021
- 11:2211:22, 9 October 2021 diff hist +429 m Hilbert's Theorem 90 →Cohomology: This section imho was severely terse! I have expanded the notation somewhat and made the definitions more self-explanatory. Also I have homogenised the notation from a mix of \phi's and \varphi's to just \phi, which I believe is what was intended.
13 September 2021
- 10:2810:28, 13 September 2021 diff hist +160 Brun sieve →Description: more adjustments of notation (see previous entries today)
- 10:1210:12, 13 September 2021 diff hist +171 Brun sieve →Description: removed redundant notation and corrected some typos
- 09:3909:39, 13 September 2021 diff hist +37 m Brun sieve →Description: a few minor changes to make the sentence clearer
24 August 2021
- 12:4212:42, 24 August 2021 diff hist +6 m Quadratic reciprocity →Legendre and his symbol: small typo
22 August 2021
- 09:5109:51, 22 August 2021 diff hist −4 m Nevanlinna theory just corrected english
27 July 2021
- 10:5310:53, 27 July 2021 diff hist +26 m Recurrence relation →Solving homogeneous linear recurrence relations with constant coefficients: just added nomenclature from older literature as this is no longer standard
11 December 2020
- 10:4410:44, 11 December 2020 diff hist −4 m Isolated singularity →Examples
- 10:4210:42, 11 December 2020 diff hist +1 m Isolated singularity →Examples: a few prepositions were strange!
- 10:3310:33, 11 December 2020 diff hist 0 m Isolated singularity →Nonisolated singularities: making it easier to read as syntax was jarring
3 December 2020
- 18:4418:44, 3 December 2020 diff hist +11 m Scheme (mathematics) →Arithmetic surfaces: just fixed small typo
17 August 2020
- 14:2814:28, 17 August 2020 diff hist +1 m Main theorem of elimination theory →A simple motivating example: fixed typo "parabola" should have been "hyperbola" current
- 14:1814:18, 17 August 2020 diff hist −7 m Main theorem of elimination theory →A simple motivating example: fixed grammar
9 August 2020
- 12:2212:22, 9 August 2020 diff hist +198 m Witt vector →History: Made the explanation involving the frobenius a little less formidable looking by invoking simple binomial coefficients
2 August 2020
- 21:5321:53, 2 August 2020 diff hist +42 m Field norm →K-th root field extensions: cleared up expression
19 June 2020
- 15:1215:12, 19 June 2020 diff hist −4 m Regular representation →Module theory point of view: typo
17 May 2020
- 10:4910:49, 17 May 2020 diff hist +28 m Jean-Pierre Serre →Honors and awards: the grammar made the meaning unclear
12 May 2020
- 14:3614:36, 12 May 2020 diff hist +19 m Kronecker symbol →Definition: the notation (although correct under some people's conventions) was inconsistent with the rest of the article -- I just fixed it
4 May 2020
- 08:3308:33, 4 May 2020 diff hist +63 m Discriminant →Product of polynomials: it looks like this had been edited at some stage in the past to swap from R = PQ as a product, to P = QR, which is less natural; as a result some of the other terms were incorrect. I have re-set it so that it is all correct and I hope R=PQ seems at least as natural a choice as P = QR, if not better!
- 08:1408:14, 4 May 2020 diff hist −3 m Resultant →Number theory: Corrected a (very important!) typo
8 March 2020
- 11:4711:47, 8 March 2020 diff hist −10 m Writhe →Numerically approximating the Gauss integral for writhe of a curve in space: fixed the english
9 February 2020
- 16:3916:39, 9 February 2020 diff hist −17 m Homotopical connectivity →Interpretation: 2 typos; and clearing up some slightly circuitous expression in the last paragraph (it's an excellent article by the way)
28 January 2020
- 14:0214:02, 28 January 2020 diff hist +400 m Braid group →Applications: Adding in anyons as a fascinating new application in the area of quantum computing
27 December 2019
- 10:2710:27, 27 December 2019 diff hist +6 m Intermediate value theorem This is phrased very well and I do not wish to disturb its flow; however with this one word I think it becomes quite a bit clearer
2 December 2019
- 21:0621:06, 2 December 2019 diff hist +76 m Resultant →Number theory: I think this was pretty much incomprehensible (!) because the indeterminates and the roots had exactly the same notation (i.e. x,y and z) :)
26 November 2019
- 15:0115:01, 26 November 2019 diff hist +25 m Resultant →Invariance under change of polynomials: tiny modifications of the English
21 October 2019
- 14:1114:11, 21 October 2019 diff hist −69 m P-adic number →Algebraic approach: oops
- 14:0914:09, 21 October 2019 diff hist +132 m P-adic number →Algebraic approach: removed the "^\times" from ZZ_p : it was wrong. To make the point which I believe that the original contributor was making (as I deduce from the preceding text), I have added in another way of phrasing the equality
15 July 2019
- 00:1300:13, 15 July 2019 diff hist −5 m Fock space →Product states, indistinguishable particles, and a useful basis for Fock space: took out the word "pure" since it is not necessary
14 July 2019
- 03:2703:27, 14 July 2019 diff hist +15 m Fock space →Product states, indistinguishable particles, and a useful basis for Fock space: definition of entangled was only correct for pure states not for mixed states
22 April 2019
- 10:3810:38, 22 April 2019 diff hist −3 m Function field of an algebraic variety corrected slightly confusing phrasing
5 April 2019
- 10:5410:54, 5 April 2019 diff hist −19 m Mutually unbiased bases I removed the line about non-orthogonality: I think that the intention to clarify is good; but in my view it is more likely to confuse a reader new to the subject in view of the definition of a basis as being a maximal orthogonal set: so to "add" that a set of new vectors cannot be orthogonal to a basis is potentially not just tautological; it would lead me to think I had misread the original definition! I also slightly clarified the next sentence.
24 December 2018
- 05:2005:20, 24 December 2018 diff hist +5 m Coastline paradox →Mathematical aspects: replaced "infinitely small" with "infinitesimally small"
- 05:1205:12, 24 December 2018 diff hist −2 m Numerical integration rectified a common, but wrong, use of the word "constitutes" (the meaning was backwards)
18 November 2018
- 16:4016:40, 18 November 2018 diff hist +121 m Elliptic curve →The modularity theorem and its application to Fermat's Last Theorem: attribution to original author
- 16:1316:13, 18 November 2018 diff hist +828 m Elliptic curve →The Birch and Swinnerton-Dyer conjecture: a couple of typos and then disambiguating the traces a_p from the coefficients a_i of the elliptic curves. Also somehow the definition of a_p itself was missing
20 September 2018
- 13:5413:54, 20 September 2018 diff hist 0 m Isomorphism theorems →Third isomorphism theorem: changed ideals to I,J and left rings as R, A rather than using A,B for subrings AND ideals ....
18 September 2018
- 12:5512:55, 18 September 2018 diff hist +37 m Quartic reciprocity →Gauss: for p = 3 ( 4 ) case just making it clear quadratic <==> biquadratic so as to make the result as stated as strong as possible
- 12:2012:20, 18 September 2018 diff hist +5 m Quadratic reciprocity →Legendre and his symbol: changed to more conventional notation
17 September 2018
- 17:0917:09, 17 September 2018 diff hist +246 m Quadratic reciprocity →Legendre and his symbol: need to justify the next line
