Abstract
The paper studies a finitely repeated Prisoner’s Dilemma. To maintain cooperation in the game, a new profile of behavior strategies is proposed, where the deviation of a player is punished not until the end of the game, but rather for a given number of stages depending on the stage of the game. The existence of an approximate equilibrium or epsilon-equilibrium in these strategies is proven, and the maximum payoff of a player deviating from the approximate equilibrium is found.

Doklady Mathematics is a journal of the Presidium of the Russian Academy of Sciences. It contains English translations of papers published in Doklady Akademii Nauk (Proceedings of the Russian Academy of Sciences), which was founded in 1933 and is published 36 times a year. Doklady Mathematics includes the materials from the following areas: mathematics, mathematical physics, computer science, control theory, and computers. It publishes brief scientific reports on previously unpublished significant new research in mathematics and its applications. The main contributors to the journal are Members of the RAS, Corresponding Members of the RAS, and scientists from the former Soviet Union and other foreign countries. Among the contributors are the outstanding Russian mathematicians.
