weird link[edit]

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)[reply]

Untitled[edit]

The family name capitalisation (CHERN) I have removed. Although I wish it were an English standard, there have been discussions about introducing it to en.WP and currently the consensus seems to be not to. If this position changes I will be more than happy to recapitalise it! VivaEmilyDavies 18:22, 9 Apr 2005 (UTC)

These web pages have newspaper obituaries

which include family details. Those seem to say that he had two children.

Name ordering[edit]

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)[reply]

GR transcription[edit]

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)[reply]

PS As a result the lead is now perhaps a bit thin. I leave it to an expert to summarize the importance of Chern's work in a sentence or two. --NigelG (or Ndsg) | Talk 13:07, 29 November 2007 (UTC)[reply]

Citations needed[edit]

Some inline citations would be useful: ie explicit references to the External links or other published sources. --NigelG (or Ndsg) | Talk 22:39, 29 November 2007 (UTC)[reply]

Is this the Chern number guy too?[edit]

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

Never mind, it redirects from Chern classes. Nerdseeksblonde (talk) 22:13, 8 October 2009 (UTC)[reply]

Huh???[edit]

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)[reply]
