Divergence is a word that can have different meanings, each of them depending on the scope or context where it is used; is a word that comes from the Latin "divergens" or "divergentis" which means "action of separating", composed of lexical elements such as the prefix "di" which refers to "multiple separation", in addition to the verb "vergere" which means "Lean" and the suffix "ia" that refers to "quality". In a general sense divergence can be described as the action and effect of diverging. One of the main meanings that the RAE exposes for this term is to refer, in a social context, to a plurality of judgments, thoughts and opinions.
In the literature there is talk of a point of divergence to refer to the “uchrony”, which is, according to the application in history, the logical reconstruction assuming non-happened events, but that may have happened, therefore it is that moment when the so-called real history and the uchronic history differ or disagree.
In mathematics and physics, divergence is widely used to refer, for example, to Gauss's theorem, also known as the divergence theorem or Gauss-Ostrogradsky theorem, which relates the flow of a vector field through a closed surface with the integral of its divergence in that volume delimited by said surface. On the other hand, there is the Kullback-Leibler divergence, which refers to an indicator of similarity that exists between two probability distribution functions. In geometry divergence is the positioning of the lines that are progressively separated from each other.
In the meteorological field, we speak of “ divergence zones ”, to refer to the regions that thanks to the winds less air enters than leaves.
Finally, in the area of finance, divergence is the dissimilarity between the development or growth of the value of a given financial product and a technical indicator.
