2. Delta set - Wikipedia

   en.wikipedia.org/wiki/Delta_set

   Delta set. In mathematics, a Δ-set, often called a Δ-complex or a semi-simplicial set, is a combinatorial object that is useful in the construction and triangulation of topological spaces, and also in the computation of related algebraic invariants of such spaces. A Δ-set is somewhat more general than a simplicial complex, yet not quite as ...

   Baby furniture refers to furniture created for babies. It is often used to help the parents of the baby keep it safe and comfortable in the home. Before baby furniture, parents would sleep with their children in their own beds, which could be dangerous for the child.

4. Gδ set - Wikipedia

   en.wikipedia.org/wiki/Gδ_set

   The zero-set of a derivative of an everywhere differentiable real-valued function on is a G δ set; it can be a dense set with empty interior, as shown by Pompeiu's construction. The set of functions in C ( [ 0 , 1 ] ) {\displaystyle C([0,1])} not differentiable at any point within [0, 1] contains a dense G δ subset of the metric space C ( [ 0 ...

7. Uniform integrability - Wikipedia

   en.wikipedia.org/wiki/Uniform_integrability

   Measure-theoretic definition. Uniform integrability is an extension to the notion of a family of functions being dominated in which is central in dominated convergence. Several textbooks on real analysis and measure theory use the following definition: [1][2] Definition A: Let be a positive measure space.
