Title  : Positively Graded Domains

Abstract : We will discuss positively graded affine domains over complex
field from algebraic, geometric, and topological viewpoints.
Important results by M. Demazure, I. Dolgachev, H. Flenner, S. Goto, A.
Grothendieck, S. Mori, W. Neumann, P. Orlik- P. Wagreich, H. Pinkham,
Keiichi Watanabe will be mentioned. A very general result
"conjectured" by me in 1990 and proved by O. Mathieu around 2003 will
be discussed. It has important consequences for rings of
invariants of reductive algebraic groups. Many naturally occurring 
examples
of positively graded domains will be
discussed.

If time permits, I will mention closely related results proved recently 
by
A. Pramanik-S. Thandar-R.V. Gurjar about affine surfaces with finite
fundamental group at infinity.
