polemos is incorrectly written, and should be written as "polemos" being its meaning:
Greek word meaning war. Also used the philosopher Heraclitus 6th century a. d. C. to describe the true nature of reality, as an internal conflict that forced her to change. This is considered the forerunner of the dialectic understood as struggle of opposites. Currently receive this classic name many cultural institutions worldwide, such as publishing houses, magazines and other associations.
