Form is not only a geometric figure in mathematics, but also includes the relations, properties and characteristics of various figures. For example, two-dimensional graphics in the area, perimeter and other attributes, three-dimensional graphics in the surface area, volume and other attributes. The study of these characteristics and properties can provide powerful mathematical support for scientific research and engineering practice.
In addition to Euclidean geometry and non-Euclidean geometry, there are many fields in mathematics involving shapes, such as calculus and topology. Curves and surfaces in calculus can also be regarded as a shape, while topology focuses on the basic characteristics of shape deformation and transformation. Therefore, it can be said that ontology is a generalized mathematical concept, which has important applications and functions in different fields.
