    Controlling population dynamics is complex. While age-dependent mortality and fertility models are generally not fully controllable, specific interventions can stabilize population levels.

    Area of Science:

    • Mathematical Biology
    • Demography
    • Population Dynamics

    Background:

    • Classical age-dependent population models incorporate age-specific fertility and total population-dependent mortality.
    • Understanding population control mechanisms is crucial for ecological and demographic stability.

    Purpose of the Study:

    • To investigate the controllability of age-dependent population models with respect to mortality function.
    • To determine conditions under which population levels can be maintained at a specified target.

    Main Methods:

    • Analysis of classical age-dependent population models.
    • Mathematical investigation of control theory applied to mortality functions.

    Main Results:

    • Age-dependent population systems are generally not completely controllable via mortality function adjustments.

  • Specific conditions exist where targeted control of mortality can stabilize population size.

    • Conclusions:

    • Complete population control is not always achievable through mortality interventions in age-dependent models.
    • Partial or conditional control strategies can be effective for population stabilization.
