This manuscript is a study of Pre A∗
-functions. Here a Pre
A∗
-function defined as a mapping f : 3
n −→ 3, where 3 = {0, 1, 2} is a
Pre A∗
-algebra. Further it has been determined various properties of Pre
A∗
-functions. Some basic properties of Pre A∗
-functions such as duality,
order relation and erstwhile properties are identified in this document.
