The media reported on Perelman's life 15 years after his refusal of the $1 million award.

Russian mathematician Grigory Perelman, who proved the Poincare hypothesis, was spotted at the Pyaterochka store. The footage is published on March 18 by 78.

According to the TV channel, Perelman currently lives modestly in an apartment in Kupchino. A mathematician prefers simple products from the nearest store.

According to the saleswoman, his purchases are usually limited to inexpensive goods.

"Well, he usually [takes] Red Price noodles, Piskarevsky cottage cheese, apples, maybe. Everything is so cheap," the woman said.
