SUMMARY:Blow-ups of weighted projective planes at a point: Exploring the\np
 arameter space of triangles and the MDS property
CLASS:PUBLIC
DESCRIPTION:JAVIER GONZÁLEZ ANAYA\, UNIVERSITY OF CALIFORNIA AT RIVERSIDE\
 n\nWe discuss the Mori dream space (MDS) property for blow-ups of toric\ns
 urfaces defined by rational plane triangles at a general point. We\nconsid
 er a parameter space of all such triangles and show how it can\nbe used to
  prove the MDS property for these varieties. Furthermore\,\nthis parameter
  space helps explain most known results in the area and\nhas also led to s
 urprising new results\, including examples of such\nsurfaces with a semi-o
 pen effective cone. This is joint work with\nJosé Luis González and Kall
 e Karu.\n\nMC 5403
