The mother of the famous mathematician Gregory Perlman has died.
87-year-old Lyubov Lyubovna passed away more than a month ago. To organize the funeral and solve problems with documents, the younger sister of the mathematician Elena flew to St. Petersburg from Sweden.
After the death of his mother, the scientist almost stopped leaving the house. But, according to the neighbors, he has long led a reclusive lifestyle - he avoids communication and tries not to meet residents, even in the elevator.
Perlman goes out for groceries about once every week and a half, but refuses offers of help.
Perlman moved in with his mother about ten years ago to take care of her. For this reason, the mathematician sold his own apartment, which he inherited from his grandmother.
