'Ricci flow invariant curvature cones'

Abstract:  Among the various notions of positive curvature conditions in 
Riemannian geometry only some are preserved by the Ricci flow. It is 
still unknown what the necessary and sufficient conditions are which 
will ensure this property. In this talk, I will discuss some results 
towards answering this question.

'Exceptional holonomies on the deformations of cones and modifications 
of the Ricci flow'.

Some basic facts on a holonomy group of a Riemannian manifold will be 
explained and some old results on constructing metrics with prescribed 
holonomy will be mentioned. Using this construction it is possible to 
define a new flow such that induced metric on the 'time-space' will be 
isometric to the Eguchi-Hanson metric.
