Died when? How about a (1931-19__) at the beginning? Twilight Realm 01:12, 4 October 2005 (UTC)

Sudarshan is alive and well in Austin, Texas, and very active in his research. The two pages on him should be merged. But note that the correct spellings are "Sudarshan". Also, one needs to list his bibliography. -MarcAurel Jan 31, 2006

Glauber-Sudarshan or Sudarshan-Glauber
I have seen both terms. But I think Glauber-Sudarshan is used more often and, therefore, I am going to change the usage in the article. MarcAurel 03:15, 25 April 2006 (UTC)

The representation was first introduced by Sudarshan, and then later adopted by Glauber (he called it P-represntation). Also, Glauber's interpreation of the P function as being a probability function is incorrect, since positive functions do not lead to interesting quantum effects.

"I have seen both terms. But I think Glauber-Sudarshan is used more often and, therefore, I am going to change the usage in the article." - That's a nice observation. However, given that it's his biography on wikipedia, I am going to change the usage in the article.

Interesting 'Formalism' Mention
I am just interested as to what work Sudarshan did in regard to the development of dynamical maps. Did he work on the analysis of dynamical maps or was he more interested in applications in physics (the answer is quite obvious given that physics would have been his major interest - but it is quite possible that he did some analytical work).

If Sudarshan published work to formalise aspects of dynamical maps work, it would be nice to see that as this might allow him to have some claim as a mathematician worthy of being put on the wikipedia listing of mathematicians.

You can find the paper at http://wildcard.ph.utexas.edu (that is his paper

(1961) Dynamical Mappings of Density Operators in Quantum Mechanics I, J. Math. Phys. 2, 772-775 (1961); with T. F. Jordan.

I think Sudarshan was interested in physics in the end, but did work out some mathmatical aspects of this and other topics.

work at IMSc Chennai
Prof E.C.G. Sudarshan worked as the Director of The Institute of Mathematical Sciences, Chennai, India for five years during the 1980s. During his tenure, he transformed it into a centre of excellence. This is worth a mention in the biography.N shaji 01:21, 29 August 2006 (UTC)

"E"
The initial was changed recently from "Ennakkal" to "Enchakkal". Do we have any reference for this ? "Ennakkal" or "Enakkal" seems more likely than "Enchakkal" as a family name for someone from Kerala as is Dr. Sudarshan. Tintin (talk) 17:08, 5 January 2007 (UTC)
 * His bio on the Texas University webpage mentions him as Ennackal Chandy George Sudarshan. I think we can assume this to be a fairly authoritative source.--thunderboltz(Deepu)  18:33, 5 January 2007 (UTC)

Removing the Indian Christian category
I deleted this category because I am aware that he has been on the board of the Meenakshi Temple in Houston for years and years. This can only mean that he considers himself to be a Hindu, which is reinforced by the fact that he frequently lectures on Vedanta. 74.230.200.124 04:35, 8 February 2007 (UTC)

It is true that he is active in the Hindu community, but he is also interested in his Christian background (Private conversations). —The preceding unsigned comment was added by Special:Contributions/ (talk)

'Pantheist'
Per WP:BLP policy, if Sudarshan is to be identified as a pantheist, we need a source where he explicitly self-identifies as such. The source cited fails to provide such explicit self-identification - and per policy, it should probably be deleted immediately. I've not done so, for now, but will do so shortly if proper sourcing isn't provided. AndyTheGrump (talk) 09:35, 30 December 2013 (UTC)
 * Deleted, keeping it Hinduism, less confusing and more appropriate too. Bladesmulti (talk) 09:41, 30 December 2013 (UTC)

" ... wrote a physicist ... "
The use of this phrase sounds like sloppy research. Here for my own extremely sloppy (but slightly more extensive) research: Google brings up an article at URL http://www.thecrimson.com/article/2005/12/6/scientists-question-nobel-a-group-of/ which ascribes these utterances to "Ranjit Nair, the director of the Centre for Philosophy and Foundations of Science in New Delhi, India", who had signed a petititon calling for recognition of Sudarshan. Could somebody more versed in physics history either see if this checks out or chuck out the whole quote? Thanks. — Preceding unsigned comment added by 95.149.109.45 (talk) 03:54, 8 December 2014 (UTC)
