DESCRIPTION:To a triangulated category one can associate a complex manifol
 d of Bridgeland stability conditions\, on which the automorphisms of the c
 ategory naturally act. Some examples have been explicitly computed but in 
 general it is difficult to do so.\n\nI will explain how to stratify the sp
 ace of stability conditions in certain cases\, and thence obtain a combina
 torial model for its homotopy type. This model can be described in terms o
 f t-structures on the triangulated category and tilting relations between 
 them. For an interesting class of cases it can be used to show that the sp
 ace of stability conditions is contractible.\n
