Inclusion set theory
WebSet Theory Sets A set is a collection of objects, called its elements. We write x2Ato mean that xis an element of a set A, we also say that xbelongs to Aor that xis in A. If Aand Bare sets, we say that Bis a subset of Aif every element of B is an element of A. In this case we also say that Acontains B, and we write BˆA.

WebGiven any family of sets F there is a poset P = ( F, { ( A, B) ∈ F 2: A ⊆ B }) corresponding to that family ordered by inclusion. Now by an "inclusion maximal/maximum/minimal/minimum" set in F what is meant is simply a maximal/maximim/minimal/minimum element of F. WebInclusion map. In mathematics, if is a subset of then the inclusion map (also inclusion function, insertion, [1] or canonical injection) is the function that sends each element of to treated as an element of. A "hooked arrow" ( U+ 21AA ↪ RIGHTWARDS ARROW WITH HOOK) [2] is sometimes used in place of the function arrow above to denote an ...
WebInclusion-Exclusion Principle with introduction, sets theory, types of sets, set operations, … WebA well-known application of the inclusion–exclusion principle is to the combinatorial problem of counting all derangements of a finite set. A derangement of a set A is a bijection from A into itself that has no fixed points.
