	The Original Barnstar
	In respectful recognition of the ongoing massive GE-status-aspirational upgrading of the representations of the Lorentz group article... can't wait for the outcome! Sort of like Obama's peace prize? The other half redeemable upon success! Cuzkatzimhut (talk) 18:05, 2 December 2016 (UTC)

		The E=mc² Barnstar
		For the creation of Derivative of the exponential map‎, a truly salutary tasteful contribution to WP. Cuzkatzimhut (talk) 12:36, 3 December 2014 (UTC)

		The Barnstar of Diligence
		For all your work on the Lorentz group and related articles. Excellent work! M∧Ŝc²ħε И_τlk 19:03, 10 April 2014 (UTC)

	The Citation Barnstar
	Hi Thank you for reverting my mistake. I was using energy momentum tensor written in this page which is not devided by c^2: Electromagnetic stress-energy tensor I think these two page have a conflict in definition! Is that true?

		The Barnstar of Diplomacy
		For your linchpin protection of wave packet and setting it back on the trail to improvement Cuzkatzimhut (talk) 21:40, 26 October 2014 (UTC)

On 2 August 2014, Did you know was updated with a fact from the article Closed subgroup theorem, which you recently created or substantially expanded. The fact was ... that John von Neumann's theorem that every closed real matrix group is a Lie group inspired Élie Cartan to prove a generalization, the closed subgroup theorem? The nomination discussion and review may be seen at Template:Did you know nominations/Closed subgroup theorem. You are welcome to check how many page hits the article got while on the front page (here's how, live views, daily totals), and it may be added to the statistics page if the total is over 5,000. Finally, if you know of an interesting fact from another recently created article, then please feel free to suggest it on the Did you know talk page.
