→Proof of the conjecture: + link to Gregorio Ricci-Curbastro
m+35
→Homeomorphism v. diffeomorphism: ditto
m→Strings, surfaces, and looping around: + em dash for en dash
→The three sphere: - typo by me
m-3
→The three sphere: + clarification: a rejoining of the exterior surface of a one-sphere is a deformation, though the action does not always result in meeting the criteria for remaining a one-sphere. + indef. art., + art./first noun-sound agreement.
+36
→Perelman's proof: placed comma after participial phrase modifying subject, it also being a phrase which precedes the subject..
+1
→Strings, surfaces, and looping around: added second comma to bracket interrupting adverbial phrase.
+1
→Perelman's proof: + corrected verb to replace plural verb with singular verb to match singular noun it predicates.
+1
→Perelman's proof: + needed comma to precede conjoining independent clauses; removed conjuction in same place between first two of three, following conjoined independent clauses "list" convention.

→Homeomorphism v. diffeomorphism: ditto
m→The three sphere: ditto
m→Layman statement of the conjecture: ditto
m→The three sphere: + consistent hyphen usage in phrase "n"-dimensional ("three-dimensional" for example)
m→The three sphere: a "plane" is one of multiple conjectured "planes" that exist: needs indefinite article; "distance" is a noun that may convey a reference to a particular one (as by the adjective "some") as the adjective "distant" cannot: substituted

ditto on using participle for ambiguous adjectival qualities + sentence case in section titles.
m+ participle tense for ambiguous adjectival quality

i think this is actually proved by some homotopy group computations

some tweaks to layman's statement, ready for further improvement! i will add comments on talk page

attempt to improve on layman statement of conjecture; please correct or improve

→Homeomorphism v. Diffeomorphism

there's no exotic S^6 (though whether S^6 admits an integrable complex structure is another major open problem!)
