Welcome![edit]
First, let me be the first to welcome you to Wikipedia! Your contributions to K-theory and KK-theory show that you're quite knowledgeable on both topics, and likely many more related ones as well, though I have placed a few templates on both of those articles. Unfortunately, it is fairly difficult for those who are unfamiliar with the topics to realize the context of both of these theories. You may wish to read over WP:LEAD for some tips on writing introductions to complex topics such as these. Keep up the good work! thadius856talk|airports|neutrality 21:35, 17 September 2007 (UTC)
