What is the simplex in the zero dimension?
In topology, Betti numbers represent the various dimensions of a topological space in regards to the number of holes that are present. There are four different simplices depending on the dimension: zero, one, two, three.
These are also referred to as:
Zero simplex refers to a point or vertex.
One simplex refers to a line or edge (which is connected by two points)
Two simplex refers to a face (which is connected by three lines)
Three simplex refers to the 3D object created by two faces.
Therefore the simplex in the zero dimension is known as a vertex.
