## updated info

Dear Urs,

The title “supermanifolds” was only a tentative one, based on what Chenchang thought I might speak about. The actual title of my talk will be “On models for the adjoint representation of a Lie algebroid”, and it will be based on this paper with Alfonso Gracia-Saz. But, to be sure, some “super” stuff will make an appearance.

I look forward to meeting you. I’m sure we’ll have a lot to talk about.
