    The course debuted in the fall of 2023, with the first exam session taking place in May 2024. The course and examination are designed to teach and assess precalculus concepts, as a foundation for a wide variety of STEM fields and careers, and are not solely designed as preparation for future mathematics courses such as AP Calculus AB/BC.

    3.3.3.3.3.3 Non-simplical fundamental domains The only possible fundamental domain in Euclidean 2-space that is not a simplex is the rectangle (∞ 2 ∞ 2), with Coxeter diagram : .

  4. Mapping class group - Wikipedia

    en.wikipedia.org/wiki/Mapping_class_group

    The term mapping class group has a flexible usage. Most often it is used in the context of a manifold M. The mapping class group of M is interpreted as the group of isotopy classes of automorphisms of M. So if M is a topological manifold, the mapping class group is the group of isotopy classes of homeomorphisms of M.

  5. Operator (mathematics) - Wikipedia

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

    The Fourier transform is useful in applied mathematics, particularly physics and signal processing. It is another integral operator; it is useful mainly because it converts a function on one (temporal) domain to a function on another (frequency) domain, in a way effectively invertible. No information is lost, as there is an inverse transform ...

  8. Stack (mathematics) - Wikipedia

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

    In mathematics a stack or 2-sheaf is, roughly speaking, a sheaf that takes values in categories rather than sets. Stacks are used to formalise some of the main constructions of descent theory, and to construct fine moduli stacks when fine moduli spaces do not exist.

  9. Convex set - Wikipedia

    en.wikipedia.org/wiki/Convex_set

    The collection of convex subsets of a vector space, an affine space, or a Euclidean space has the following properties: [9] [10] The empty set and the whole space are convex. The intersection of any collection of convex sets is convex. The union of a sequence of convex sets is convex, if they form a non-decreasing chain for inclusion.
