Modular unit
{{Short description|Concept in mathematics}}
In mathematics, modular units are certain units of rings of integers of fields of modular functions, introduced by {{harvs|txt|last=Kubert|authorlink=Daniel Kubert|last2=Lang|author2-link=Serge Lang|year=1975}}. They are functions whose zeroes and poles are confined to the cusps (images of infinity).
