Multiplayer Evolutionary Games (MEGs) extend classical evolutionary game theory by incorporating interactions among multiple participants rather than just two. This lecture introduces MEGs and their foundational connection to population genetics and their evolutionary dynamics. Theoretical principles such as fitness, selection, and mutation are explored, illustrating how MEGs capture non-linear interaction effects. The importance of higher-order interactions is emphasized, demonstrating how MEGs naturally extend traditional evolutionary models to more complex, real-world scenarios.

In this talk I will discuss the energy probability density function of an evaporating near-extremal charged black hole. At sufficiently low energies, such black holes experience large quantum metric fluctuations in the $AdS_{2}$ throat which are governed by a Schwarzian action. These fluctuations modify Hawking evaporation rates, and therefore also affect how the black hole state evolves over time. In previous work on Schwarzian-corrected Hawking radiation, the black hole was taken to be in the microcanonical or canonical ensemble [arXiv:2411.03447]. However, we find that an initially fixed-energy or fixed-temperature state does not remain so in the regime where Schwarzian corrections are important. We consider three decay channels: the emission of massless scalars, photons, and entangled pairs of photons in angular momentum singlet states. In each of the three cases, we find that in the very low energy, quantum dominated regime, the probability distribution of the black hole energy level occupation tends toward a particular attractor function that effectively depends on only one combination of time and energy. This function is independent of the initial state and gives new predictions for the energy fluxes and Hawking emission spectra of near-extremal charged black holes.
