User talk:Yuide

Hi, regarding your editing Haggstrom's name in FKG inequality, if you change a reference like that, you also have to change the citations pointing to it, since it is now broken. This might be a disadvantage of the method of citation used there, but in a math article I prefer this to footnotes... And, by the way, the o also needs an umlaut in his name, ström. --GaborPete (talk) 05:44, 8 April 2010 (UTC)

Rhombic dodecahedron
I reverted this from Rhombic dodecahedron:
 * The result of identifying 'geometrically opposite' vertices in the graph given by the edges of the dodecahedron is the Petersen graph.

I think this is true for the regular dodecahedron which has 20 vertices. The peterson graph has 10 nodes, so couldn't be related to the (14 vertex) rhombic dodecahedron by identifying opposites together. SockPuppetForTomruen (talk) 21:45, 21 September 2011 (UTC)

You're right - I've added it to the right place now. Yuide (talk) 11:15, 22 September 2011 (UTC)

Now I reaIized it's not even true. Removed. So much for that edit :p Yuide (talk) 11:19, 22 September 2011 (UTC)

RSK
Hi Yuide, Thanks for your contribution to the article on RSK. If you look at the context in which you added the material, though, you'll see that it's in the section on symmetric matrices, while most of the facts you mention are about the different special case of permutation matrices; also, much of what you've added there is already in the section on the permutation case, and/or in the related article Robinson-Schensted correspondence. Perhaps you could try to reorganize your addition in a way that reflects this? Thanks! All the best, JBL (talk) 13:54, 12 December 2012 (UTC)

Hi Yuide, If I'm reading the change log correctly, you assert that the descent set of a word is the same as that of its Q-tableau under RSK. Do you have a reference for that fact? It is easy to prove with the dual Knuth moves, for instance, but I'd like to know who first noticed it. I haven't been able to find it stated explicitly in the literature anywhere other than here. (As it happens I need this reference for a paper I'm writing, which is why I noticed - but it would be good to have on here, too). Best, Speedymollusc (talk) 00:09, 3 January 2013 (UTC)


 * I'm moderately confident that it's in Ch7 of Stanley's EC2. --JBL (talk) 01:57, 3 January 2013 (UTC)


 * Aha! You are right.  It is Lemma 7.23.1 of EC2.  It is apparently due originally to Schutzenberger and independently rediscovered by Foulkes, according to the remarks on p.404.  Thanks! Speedymollusc (talk) 21:15, 3 January 2013 (UTC)


 * I have apparently been logged off for some time. I made the move now. I found the descent set property in an appendix in Björner and Brentis book. Yuide (talk) 12:23, 16 January 2013 (UTC)

Your account will be renamed
Hello,

The developer team at Wikimedia is making some changes to how accounts work, as part of our on-going efforts to provide new and better tools for our users like cross-wiki notifications. These changes will mean you have the same account name everywhere. This will let us give you new features that will help you edit and discuss better, and allow more flexible user permissions for tools. One of the side-effects of this is that user accounts will now have to be unique across all 900 Wikimedia wikis. See the announcement for more information.

Unfortunately, your account clashes with another account also called Yuide. To make sure that both of you can use all Wikimedia projects in future, we have reserved the name Yuide~enwiki that only you will have. If you like it, you don't have to do anything. If you do not like it, you can pick out a different name. If you think you might own all of the accounts with this name and this message is in error, please visit Special:MergeAccount to check and attach all of your accounts to prevent them from being renamed.

Your account will still work as before, and you will be credited for all your edits made so far, but you will have to use the new account name when you log in.

Sorry for the inconvenience.

Yours, Keegan Peterzell Community Liaison, Wikimedia Foundation 04:09, 20 March 2015 (UTC)
