In mathematics, especially in topology, equidimensionality is a property of a space that the local dimension is the same everywhere.
[1] A topological space X is said to be equidimensional if for all points p in X, the dimension at p, that is dim p(X), is constant.
A scheme S is said to be equidimensional if every irreducible component has the same Krull dimension.
For example, the affine scheme Spec k[x,y,z]/(xy,xz), which intuitively looks like a line intersecting a plane, is not equidimensional.
