From Academic Kids

In the absence of a more specific context, Convergence denotes the approach toward a definite value, as time goes on; or to a definite point, a common view or opinion, or toward a fixed or equilibrium state.

Mathematics

In mathematics, convergence describes limiting behaviour, particularly of an infinite sequence or series toward some limit. To assert convergence is to claim the existence of such a limit, which may be itself unknown. For any fixed standard of accuracy, however, you can always be sure to be within that limit, provided you have gone far enough. The following lists more specific usages of this word:

The opposite of convergence is divergence. Divergence may be some kind of oscillation, unrestricted growth (recognised as the case of an infinite limit), or chaotic behavior. An infinite series that is divergent cannot be used for meaningful computations of its value. Nevertheless, divergent series can be summed formally, as generating functions or asymptotic series, or via some summation method.

  • Language convergence pertains to the blending of two languages that are perceived as having equal social status. Opposite of Non-convergent discourse.
  • Non-convergent discourse pertains to the persistence of asymmetric or bilingual discourse in natural languages.
  • Catch-up effect is otherwise known as the Theory of convergence in economic theory.
  • In the context of bargaining, Convergence pertains to a behavior in which the price offered by a buyer may increase while the price acceptable to a seller may decrease until both prices approach equality, in which case they are said to converge.
