John F. Nash Jr., a mathematician who shared a Nobel Prize in 1994 for work that greatly extended the reach and power of modern economic theory and whose decades-long descent into severe mental illness and eventual recovery were the subject of a 2001 film, “A Beautiful Mind,” was killed in a car crash Saturday in New Jersey. He was 86.
