👉 In mathematics, a homoplasy is defined as an algebraic structure where every element has exactly one inverse. This means that for any two elements x and y in the structure, there exists at least one other element z such that x = y and z = -y. The term "homoplasis" comes from its similarity to the concept of homomorphisms in group theory, which can be thought of as an algebraic operation between two structures where the result is itself a structure.
