Proof of the Refined Alternating Sign Matrix Conjecture

نویسنده

  • Doron Zeilberger
چکیده

Mills, Robbins, and Rumsey conjectured, and Zeilberger proved, that the number of alternating sign matrices of order n equals A(n) := 1!4!7! · · · (3n − 2)! n!(n + 1)! · · · (2n − 1)! . Mills, Robbins, and Rumsey also made the stronger conjecture that the number of such matrices whose (unique) ‘1’ of the first row is at the rth column equals A(n) `n+r−2 n−1 ́`2n−1−r n−1 ́ `3n−2 n−1 ́ . Standing on the shoulders of A. G. Izergin, V. E. Korepin, and G. Kuperberg, and using in addition orthogonal polynomials and q-calculus, this stronger conjecture is proved.

Three alternating sign matrix identities in search of bijective proofs

These are rich combinatorial objects with connections to many problems in algebraic combinatorics (see [2], [3], [12]). They also have many different representations. The representation that was used in Kuperberg’s proof of the counting function for alternating sign matrices [9] and Zeilberger’s proof of the refined alternating sign matrix conjecture [14] is the six-vertex model of statistical ...

New enumeration formulas for alternating sign matrices and square ice partition functions

The refined enumeration of alternating sign matrices (ASMs) of given order having prescribed behavior near one or more of their boundary edges has been the subject of extensive study, starting with the Refined Alternating Sign Matrix Conjecture of Mills-Robbins-Rumsey [25], its proof by Zeilberger [31], and more recent work on doublyrefined and triply-refined enumeration by several authors. In ...

A refined Razumov-Stroganov conjecture

We extend the Razumov-Stroganov conjecture relating the groundstate of the O(1) spin chain to alternating sign matrices, by relating the groundstate of the monodromy matrix of the O(1) model to the so-called refined alternating sign matrices, i.e. with prescribed configuration of their first row, as well as to refined fully-packed loop configurations on a square grid, keeping track both of the ...

Truncated determinants and the refined enumeration of Alternating Sign Matrices and Descending Plane Partitions

In these notes, we will be mainly focussing on the proof of the so-called ASM-DPP conjecture of Mills, Robbins and Rumsey [22] which relates refined enumerations of Alternating Sign Matrices (ASM) and Descending Plane Partitions (DPP). ASMs were introduced by Mills, Robbins and Rumsey [24] in their study of Dodgsons condensation algorithm for the evaluation of determinants. DPPs were introduced...

A new proof of the refined alternating sign matrix theorem

Abstract. In the early 1980s, Mills, Robbins and Rumsey conjectured, and in 1996 Zeilberger proved a simple product formula for the number of n × n alternating sign matrices with a 1 at the top of the i-th column. We give an alternative proof of this formula using our operator formula for the number of monotone triangles with prescribed bottom row. In addition, we provide the enumeration of cer...
