Vladimir Voevodsky, formerly a gifted but restless student who flunked out of college out of boredom before emerging as one of the most brilliant and revolutionary mathematicians of his generation, died on Sept. 30 at his home in Princeton, N.J. He was 51.
Nadia Shalaby, his former wife, said he was found dead in his home by friends, whom she had called when she had not heard from him. They then called the police. He had been ill and had apparently collapsed, she said, but the exact cause of death had not been determined.
