  2. Three-dimensional space - Wikipedia

    en.wikipedia.org/wiki/Three-dimensional_space

    In geometry, a three-dimensional space (3D space, 3-space or, rarely, tri-dimensional space) is a mathematical space in which three values (coordinates) are required to determine the position of a point. Most commonly, it is the three-dimensional Euclidean space, that is, the Euclidean space of dimension three, which models physical space.

    For a formal statement of the theorem, let : be a continuous map from a compact triangulable space to itself. Define the Lefschetz number [2] of by := ((,)), the alternating (finite) sum of the matrix traces of the linear maps induced by on (,), the singular homology groups of with rational coefficients.

  4. Investigations in Numbers, Data, and Space - Wikipedia

    en.wikipedia.org/wiki/Investigations_in_Numbers...

    Investigations was developed between 1990 and 1998. It was just one of a number of reform mathematics curricula initially funded by a National Science Foundation grant. The goals of the project raised opposition to the curriculum from critics (both parents and mathematics teachers) who objected to the emphasis on conceptual learning instead of instruction in more recognized specific methods ...

    en.wikipedia.org/wiki/Space_(mathematics)

    The third-level classification distinguishes, for example, between spaces of different dimension, but does not distinguish between a plane of a three-dimensional Euclidean space, treated as a two-dimensional Euclidean space, and the set of all pairs of real numbers, also treated as a two-dimensional Euclidean space. Likewise it does not ...

    en.wikipedia.org/wiki/Manifold_alignment

    Manifold alignment is a class of machine learning algorithms that produce projections between sets of data, given that the original data sets lie on a common manifold.The concept was first introduced as such by Ham, Lee, and Saul in 2003, [1] [non-primary source needed] adding a manifold constraint to the general problem of correlating sets of high-dimensional vectors.

    In mechanics and geometry, the 3D rotation group, often denoted SO(3), is the group of all rotations about the origin of three-dimensional Euclidean space under the operation of composition.
