I have several issues with this section, which I hope to either find the time and expertise to address personally, or else draw the attention of someone more skilled. Here are some potential issues:

-Going back and forth between definition and example. Giving an example after the full explanation is preferable.

-Overuse of cluttered inline typesetting. No nice paragraphs or breaks in style. Compare with nicely set first section of this article.

-Introduction of abbreviations like "Sym" and "End" without definition or blue-link

-Use of the word "clearly" which "clearly" violates Wikipedia style :)

As I said, I hope to address these issues in the future if no one more qualified comes to save the day. Lily.r.s ( talk) 06:50, 12 March 2014 (UTC) reply

It seems there is a mistake in the preamble. Over a field ${\displaystyle k}$ of characteristic 0, If ${\displaystyle \lambda }$ is a partition of ${\displaystyle n}$ and ${\displaystyle c_{\lambda }}$ is a Young symmetrizer, then it is ${\displaystyle k(S_{n})c_{\lambda }}$ that is going to be an irreducible representation of ${\displaystyle S_{n}}$. The image ${\displaystyle c_{\lambda }V^{\otimes n}}$ of ${\displaystyle c_{\lambda }}$ in ${\displaystyle V^{\otimes n}}$, which is what is written in the preamble, is instead an irreducible representation of ${\displaystyle GL(V)}$. I am hoping someone could confirm this.

It's basically just a bunch of stuff copied word-for-word out of Fulton and Harris's book with no additional explanation, quotation marks, or citation. 199.249.110.232 ( talk) 02:29, 17 March 2018 (UTC) reply

Well, the definitions and the constructions are pretty much the same across any references (and Wikipedia isn't a place to introduce a cool new construction). Do you have any specific materials that you think can be added? -- Taku ( talk) 02:52, 17 March 2018 (UTC) reply
