Mathematics
- Vertex (geometry)
In geometry, a vertex is a special kind of point which describes the corners or intersections of geometric shapes. Vertices are commonly used in computer graphics to define the corners of surfaces in 3D models, where each such point is given as a vector.-Of an angle:The vertex of an angle is the...
, a corner point of a polygon, polyhedron, tesselation, etc.
- Vertex (graph theory)
In graph theory, a vertex or node is the fundamental unit out of which graphs are formed: an undirected graph consists of a set of vertices and a set of edges , while a directed graph consists of a set of vertices and a set of arcs...
, a node in a graph
- Vertex (curve)
In the geometry of curves a vertex is a point of where the first derivative of curvature is zero. This is typically a local maximum or minimum of curvature. Other special cases may occur, for instance when the second derivative is also zero, or when the curvature is constant...
, a local extreme point of curvature

- Vertex model
A vertex model is a type of statistical mechanics model in which the Boltzmann weights are associated with a vertex in the model . This contrasts with a nearest-neighbour model, such as the Ising model, in which the energy, and thus the Boltzmann weight of a statistical microstate is attributed to...
in statistical mechanics, a discrete model of a physical system in which weights are associated with vertices of a grid graph.
