Trees (set theory)

Honest leftmost branch

In set theory, an honest leftmost branch of a tree T on ω × γ is a branch (maximal chain) ƒ ∈ [T] such that for each branch g ∈ [T], one has ∀ n ∈ ω : ƒ(n) ≤ g(n). Here, [T] denotes the set of branches of maximal length of T, ω is the smallest infinite ordinal (represented by the natural numbers N), and γ is some other ordinal. (Wikipedia).

Proof: Two-Sided Inverse Functions are Unique

Functions with a Two-Sided Inverse are Bijective

One way to prove that a function is bijective is to find a two-sided inverse function. In this video, we explain why having a two-sided inverse means that a function is a bijection! Subscribe to see more new math videos! Music: OcularNebula - The Lopez

Normal subgroups

Before we carry on with our coset journey, we need to discover when the left- and right cosets are equal to each other. The obvious situation is when our group is Abelian. The other situation is when the subgroup is a normal subgroup. In this video I show you what a normal subgroup is a
