Talk:Shiing-Shen Chern

message: Hi, at the bottom of the page there is a link to Themistocles M. Rassias in the "see also" section. The only reason for this seems to be that Chern was Rassias co-advisor. Chern has a LOT of students several of which are probably more notable. Could someone remove that link??  —Preceding unsigned comment added by 130.237.41.75 (talk) 10:57, 4 January 2011 (UTC)

message: I have moved the article back to Shiing-Shen Chern, as this Western order is the one used in mathematics, and Chern is not known under other orderings of his name. This is similar to Shing-Tung Yau or Fanghua Lin or Yuan T. Lee or Gang Tian, and standard convention in mathematics. Kusma (討論) 08:18, 16 October 2006 (UTC)

message: I've come across this page via a link from the GR Talk page.  It's always nice to learn of someone using GR to spell their name!  However, a detailed discussion of the technicalities of Chinese romanization certainly doesn't belong in the lead section of this article.  I've now rearranged the article somewhat & moved the new Transliteration section further down. --NigelG (or Ndsg) | Talk 12:58, 29 November 2007 (UTC)

Observation of unidirectional backscattering-immune
topological electromagnetic states
Zheng Wang1*, Yidong Chong1{*, J. D. Joannopoulos1 & Marin Soljacˇic´1
To detect the possible
presence of non-trivial topological band properties in a photoniccrystal
system it is sufficient5–7 to compute its Chern numbers.
(Although the original proposal5,6 focused on ‘Dirac points’, it is
not necessary to restrict to such band structures; thus, the use of a
variety of photonic-crystal systems is possible7.) The Chernnumber of
band n of a two-dimensional (2D) periodic photonic crystal is an
integer defined by6

photonic crystals. Phys. Rev. A 78, 033834 (2008).
Never mind, it redirects from Chern classes. Nerdseeksblonde (talk) 22:13, 8 October 2009 (UTC)

message: The section Research contains this "sentence":
"Chern classes, the complexification of Pontryagin classes, which have found wide-reaching applications in modern physics, especially string theory, quantum field theory, condensed matter physics, in things like the magnetic monopole."
First of all, this "sentence" is not a sentence, because there is no verb that applies to the subject ("Chern classes").
But mathematically speaking, it is simply incorrect.
Rather: The Pontryagin classes of a real vector bundle π are the (even-indexed) Chern classes of the complexified version of the bundle π. 2601:200:C000:1A0:80D8:6B79:C0AF:2203 (talk) 01:37, 3 January 2023 (UTC)
