IPA: //haɪpərˈfʌŋkʃən//
KK: /haɪpərˈfʌŋkʃən/
A concept in mathematics that refers to a generalization of a function, often used in advanced mathematical contexts.
In advanced calculus, hyperfunction theory provides a new way to understand complex functions.
Hyperfunction is formed from "hyper-" (meaning over or excessive) and "function" (from Latin "functio", meaning performance or execution). The word describes a state of excessive or over-performance in a particular function or activity.
Think of 'hyper-' meaning 'over' and 'function' referring to 'performance' — this helps you remember that hyperfunction means an excessive performance of a function.
