چکیده

We give new proofs of two theorems of Stanley on generating functions for the integer points in rational cones. The first, Stanley’s reciprocity theorem, relates the rational generating function σv+K(x) := ∑ m∈v+K∩Z x m, where K is a rational cone and v ∈ R, with σ−v+K◦(1/x). The second theorem asserts that the generating function of the Ehrhart quasipolynomial LP(n) := # (

Irrational proofs for three theorems of Stanley

We give new proofs of three theorems of Stanley on generating functions for the integer points in rational cones. The first, Stanley’s Reciprocity Theorem, relates the rational generating function σv+K(x) := ∑ m∈v+K∩Z x m, where K is a rational cone and v ∈ R, with σ−v+K◦(1/x). The second, Stanley’s Positivity Theorem, asserts that the generating function of the Ehrhart quasipolynomial LP(n) :=...

The Concept of Sub-independence and Its Application in Statistics and Probabilities

 Many Limit Theorems, Convergence Theorems and Characterization Theorems in Probability and Statistics, in particular those related to normal distribution , are based on the assumption of independence of two or more random variables. However, the full power of independence is not used in the proofs of these Theorems, since it is the distribution of summation of the random variables whic...

The Number of Linear Extensions of Ranked Posets

We revisit the question of counting the number of linear extensions of the Boolean lattice, relating this to the polyhedral methods of Kahn and Kim, and of Stanley. We give simpler proofs of various known results, and give an upper bound on the number of linear extensions of an arbitrary ranked poset satisfying the LYM condition. [Note: This preprint is not intended for journal publication, as ...

Theorems, Problems and Conjectures

These notes are designed to offer some (perhaps new) codicils to related work, a list of problems and conjectures seeking (preferably) combinatorial proofs. The main items are Eulerian polynomials and hook/contents of Young diagram, mostly on the latter. Formulas analogues to or in the spirit of works by Han, Nekrasov-Okounkov and Stanley are distributed throughout. Concluding remarks are provi...

On a special class of Stanley-Reisner ideals

For an $n$-gon with vertices at points $1,2,cdots,n$, the Betti numbers of its suspension, the simplicial complex that involves two more vertices $n+1$ and $n+2$, is known. In this paper, with a constructive and simple proof, wegeneralize this result to find the minimal free resolution and Betti numbers of the $S$-module $S/I$ where  $S=K[x_{1},cdots, x_{n}]$ and $I$ is the associated ideal to ...
