Thanks, but no thanks.

As we discussed here, the Clay Institute offered Perelman the $1,000,000 prize for solving one of their Millennium Problems.  Dr. Kornelson gave a link in the comments to that post to an article which claimed he planned to turn down the prize.

Now it’s official.

A couple of days ago the Clay Institute posted an announcement on their webpage officially announcing Dr. Perelman’s decision to decline the prize.  See here for more information.  The Clay Institute also says:

In the fall of 2010, CMI will make an announcement of how the prize money will be used to benefit mathematics.
