The Penrose Transform for Complex Projective Space
This was a Blackboard Talk. In January 2012 I'll give a similar talk at Tufts by computer projection and the slides will be available on this site. I talked about various developments starting with

Some Examples of the Penrose Transform,

which was a talk given on 30th June 1997 at RIMS in Kyoto, followed by

M.G. Eastwood, The Penrose transform for complex projective space, Complex Var. Elliptic Equ. 54 (2009), 253-264,

and by as yet unpublished joint work with Joseph Wolf.
