  1. Math: Restriction on the limits of applicability of an equation. In a differential equation, conditions that allow to fix the constant of integration and reach a unique solution. The number of boundary conditions necessary to determine a solution matches the order of the equation.

  2. Physics: Conditions needed to determine the evolution of a system, given the physical laws.
