  2. Mouse (set theory) - Wikipedia

    en.wikipedia.org/wiki/Mouse_(Set_Theory)

    In set theory, a mouse is a small model of (a fragment of) Zermelo–Fraenkel set theory with desirable properties. The exact definition depends on the context. In most cases, there is a technical definition of "premouse" and an added condition of iterability (referring to the existence of wellfounded iterated ultrapowers): a mouse is then an iterable premouse.

  3. Morse theory - Wikipedia

    en.wikipedia.org/wiki/Morse_theory

    The notion of a Morse function can be generalized to consider functions that have nondegenerate manifolds of critical points. A Morse–Bott function is a smooth function on a manifold whose critical set is a closed submanifold and whose Hessian is non-degenerate in the normal direction. (Equivalently, the kernel of the Hessian at a critical ...

    The function () = | {, …,} |, assigning densities to sufficiently well-behaved subsets {,,, …}, is a set function. A probability measure assigns a probability to each set in a σ-algebra . Specifically, the probability of the empty set is zero and the probability of the sample space is 1 , {\displaystyle 1,} with other sets given ...

    en.wikipedia.org/wiki/Functor

    In mathematics, specifically category theory, a functor is a mapping between categories.Functors were first considered in algebraic topology, where algebraic objects (such as the fundamental group) are associated to topological spaces, and maps between these algebraic objects are associated to continuous maps between spaces.
