ORBIFOLD Meaning and
Definition
-
An orbifold is a mathematical concept that combines the properties of both a manifold and a group. It is a topological space that exhibits certain symmetry group actions, known as reflections, rotations, or translations, which are defined on each point of the space. The symmetries of an orbifold can be visualized as a collection of transformations that preserve the geometric structure of the space.
An orbifold is characterized by having singular points, also referred to as cone points, where the symmetries may not act freely. These singularities are inherent to an orbifold and distinguish it from a smooth manifold. The singularities can be visualized as points, lines, or higher-dimensional subspaces, depending on the dimension of the orbifold.
The concept of an orbifold is often used in various areas of mathematics, including geometry, topology, and theoretical physics. It provides a powerful framework for understanding and classifying spaces with symmetries. By studying the symmetries of an orbifold, mathematicians can gain insights into its geometric properties and classify different types of orbifolds.
Orbifolds also allow for the study of quotients, where spaces are obtained by dividing a larger space by a group of symmetries. They provide a generalization of both smooth manifolds and quotient spaces, allowing for more flexible and nuanced mathematical structures.
In summary, an orbifold is a topological space with a group of symmetries acting on it, featuring singular points that are crucial to its definition and classification. It provides a framework for studying and understanding spaces with symmetry and has applications across various mathematical disciplines.

Etymology of ORBIFOLD
The word "orbifold" is a combination of two terms; "orbi" and "fold".
The term "orbi" is derived from the Latin word "orbis", which means "circle" or "orbit". This prefix is often used in scientific terms to refer to anything related to spheres or circular shapes, such as orbits or spherical objects.
The term "fold" is derived from the Old English word "fealdan", meaning "to bend" or "to crease". It refers to the action of folding or bending one or more two-dimensional surfaces in a specific way to create a three-dimensional structure.
In mathematics, the term "orbifold" was coined by the mathematician William Thurston in the 1970s to describe a type of geometric object that generalizes the concept of a manifold (a topological space that locally resembles Euclidean space of a specific dimension).
