But at the moment of his putative triumph, Dr. Perelman is nowhere in sight. He is an odds-on favorite to win a Fields Medal, math’s version of the Nobel Prize, when the International Mathematics Union convenes in Madrid next Tuesday. But there is no indication whether he will show up. 
reminds of me school, fucntional semantic, when the teacher told us she would give an A to the one who can solve pointcarr?'s.
