XANTHOPOULOS INTERNATIONAL AWARD
THE SELECTION COMMITTEE having taken into account the nominations for the award and 1993 Xanthopoulos Award Professor of Physics at University of California at Santa Barbara for his wide ranging contributions to the mathematical aspects of gravitational physics, in particular: i) his work on positive energy theorems in general relativity; ii) his influential ideas on global problems in general relativity such as cosmic censorship and topology change; and iii) his numerous contributions which have illuminated the global properties of spacetime geometry in string theory. Professor Horowitz's papers on String Theory and related areas have played a seminal role in bridging the gap betweem general relativity and particle physics in recent years and enriched both fields.
