This seemed like an interesting problem so I did some thinking about it. I realized that the case where one of these "second intersections" is really the point of tangency is ( Read more... )

The contangent bundle of T is self-adjoint.

Not that it's actually possible to know too much math, I just wanted a catchy title.

So yeah, I finally created an account.  There was a long time when I didn't really see the point of a diary much less one publicly accessible, but I've determined several reasons to change my mind ( Read more... )
