[sage-support] How can I test if two symbolic expressions coincide?

2012-09-13 Thread Christian Stump
Hello, can anyone tell me how I can use sage to check that the following two (fairly simple) expressions coincide. Some unneeded background: both come from identities in character theory for complex reflection groups, Sage was able to solve similar expressions, see below, and this is the smalle

Two days ago I tried to post on this list, using the UI of google groups. The message did not appear on sage-support if one views it on google groups, and still can't be seen. However, on gmane the message appeared, so I guess it also appeared to people who subscribed via E-Mail. Anyhow, I wi
