Nettet1. nov. 1989 · We present two q-analogues of a hook length formula of Knuth for the number of linear extensions of a partially ordered set whose Hasse diagram is a rooted forest.These q-analogues give formulas for the inversion index and the major index generating functions over permutations which correspond to linear extensions of a … In order theory, a branch of mathematics, a linear extension of a partial order is a total order (or linear order) that is compatible with the partial order. As a classic example, the lexicographic order of totally ordered sets is a linear extension of their product order. Se mer Linear extension of a partial order A partial order is a reflexive, transitive and antisymmetric relation. Given any partial orders $${\displaystyle \,\leq \,}$$ and $${\displaystyle \,\leq ^{*}\,}$$ on a set $${\displaystyle X,}$$ Se mer The order extension principle is constructively provable for finite sets using topological sorting algorithms, where the partial order is … Se mer The statement that every partial order can be extended to a total order is known as the order-extension principle. A proof using the axiom of choice was first published by Edward Marczewski (Szpilrajin) in 1930. Marczewski writes that the theorem had … Se mer Counting the number of linear extensions of a finite poset is a common problem in algebraic combinatorics. This number is given by the leading coefficient of the order polynomial multiplied … Se mer
Nettet20. okt. 2015 · 1 Answer. Given your finite poset P, it is clear that the first element in your linear extension must be a minimal element (else you'll not have a linear extension). Moreover, if you picked a partial linear extension -- elements a 1, …, a k ∈ P with the property that a i < a j in P implies i < j (for 1 ≤ i, j ≤ k ), then the next ...

The best known connection between partial orders and linear orders is the Szpilrajn theorem: Any partial order on a set can be extended to a linear order on the same set. From this, it follows that any partial order is the intersection of its linear extensions; equivalently, every ordered set can be represented as some subset of a ...
