the quality, of depth or thickness, that differentiates a solid object from a two-dimensional image of it

(algebraic geometry) The fourth coordinate indicating a position along the fourth axis. / (physics) The dimension of time.

(mathematical analysis) A type of fractal dimension, a real-valued measure of a geometric object that assigns 1 to a line segment, 2 to a square and 3 to a cube. Formally, given a metric space X and a subset of X labeled S, the Hausdorff dimension of S is the infimum of all real-valued d for which the d-dimensional Hausdorff content of S is zero.

(mathematical analysis) A dimension in which it is the most suitable to make measurements on a fractal set.

plural of fractal dimension

Natural stone or rock that has been fabricated to a specific shape or size.

plural of Iitaka dimension

(algebraic geometry) The Iitaka dimension of a line bundle L on an algebraic variety X is the dimension of the image of the rational map to projective space determined by L.
