Polysystem theory
The polysystem theory, a theory in the field of translation studies, implies using polyvalent factors as an instrument for explaining the complexity of culture within a single community and between communities. Analyzing sets of relations in literature and language, it gradually shifted towards a more complex analysis of socio-cultural systems. 

The polysystem theory has been embraced by students of literature and culture all over the world.

Its foremost advocate is Israeli linguist Itamar Even-Zohar. American scholar Edwin Gentzler is another important contributor to this viewpoint.
