Weintrauben, Polynome, Tableaux
… Es ist die erzeugende Funktion von Tableaux mit vorgegebenen Eigenschaften. In dieser Arbeit wird eine neue kombinatorische Struktur definiert (= Weintrauben). Die Vermutung ist, dass ein Schubert Polynom die erzeugende Funktion spezieller Weintrauben ist. Dies wird für ein Teil der …

Rectification of Composition Tableaux
… Rectification of reverse semi-standard Young tableaux is used to define evacuation of reverse semi-standard Young tableaux. We define evacuation for composition tableaux using our rectification process for composition tableaux.

Combinatorics of ribbon tableaux
… ... Which are generating functions for ribbon tableaux (hereon called ribbon functions), first defined by Lascoux, Leclerc and Thibon. Following work of Fomin and Greene, I introduce a set of operators called ribbon Schur operators on the space of partitions. I develop the theory of ribbon …

Prism tableaux and alternating sign matrices
… formula as a weighted sum over semistandard tableaux. In joint work with A. Yong, the author introduced prism tableaux. A prism tableau consists of a tuple of tableaux, positioned within an ambient grid. With A. Yong, the author gave a formula for Schubert polynomials using prism tableaux. We …

Algebraic and combinatorial properties of minimal border strip tableaux
… of Stanley concerning minimal border strip tableaux of partitions, we present three results. First we generalize the rank of a partition [lambda] to the rank of a shifted partition S([lambda]).We show that the number of bars required in a minimal bar tableau of S([lambda]) is max(o, e + …

Mixed volumes of hypersimplices, root systems and shifted young tableaux
… the study of certain patterns in standard Young tableaux of shifted shapes. For the staircase shape, Postnikov found a bijection between vectors formed by the diagonal entries of these tableaux and lattice points of the (standard) associahedron. Using similar techniques, we generalize this result …

Pattern avoidance for alternating permutations and reading words of tableaux
… pattern, and of the reading words of Young tableaux of any skew shape avoiding any of the patterns 132, 213, 312, or 231. Our bijections include a simple bijection involving binary trees, variations on the Robinson-Schensted-Knuth correspondence, and recursive bijections established via …

Sergei Rachmaninoff: Understanding the Composer Through the Etudes-Tableaux, OP. 33
… signed his own name in the music. In the Etudes-Tableaux, Rachmaninoff consistently employs specific compositional elements which contribute to the creation of his unique musical signature. By examining these aspects in the Etudes-Tableaux, many of the stylistic characteristics which permeate …

The Koszul dual to n-Lie, n-Com algebras, and Young tableaux
… which are just rooted trees with a local Young tableaux structure at each edge following what is happening in the $n$-Com operad. In particular, we use these to give an upper bound to the arities of the dimension for the operad $n\text{-}Com_d$, which gives a description for it.

La sélection de modèles linéaires appliquée aux tableaux de contingence : une approche bayésienne hiérarchique
… introduisons quelques notions de base sur les tableaux de contingence, nous voyons comment passer d'un tableau de contingence à un modèle linéaire et enfin nous tentons de réduire la dimension de l'espace des paramètres du modèle linéaire en utilisant quatre critères de sélection connus. Dans …

The Cinematic Treatment of <i>Tableaux Vivants</i> in D.W. Griffith’s <i>Broken Blossoms</i>
… and is considered to be an exemplary film in <em>Tableaux Vivants</em><a title="">[1]</a> usage. When this <em>Tableau </em>skillfully employed, the effect can be dramatic, for it bridges the gap between theatre, sculpture, literature, and poetry. To better understand how <em>Tableau</em> works in …

K-theoretic Schubert calculus and applications
… work is based on the combinatorics of genomic tableaux, which we introduce, and a generalization of M.-P. Schuetzenberger's jeu de taquin. We further apply genomic tableaux to obtain new rules in non-equivariant K-theory for Grassmannians and maximal orthogonal Grassmannians, as well as to make …

A Cornucopia Of Labeled Diagrams And Their Generating Polynomials
Combinatorics on tableaux-like objects and understanding the relationships of various polynomial bases with each other are classical explorations in algebraic combinatorics. This type of exploration is the focus of this dissertation. In the world of symmetric polynomials and their corresponding …

A Novel Insertion Algorithm
… between permutations and certain kinds of tableaux. We will define two versions of each algorithm covered, both the existing ones and the novel one. These different constructions will include one using a lot of small intermediate steps and one which directly creates the tableaux from the …

Apple girl : ingesting and transforming Apple girl from fairy tale into sculpture and performance

Branching from K to M for split classical groups

Frontiers of Conditional Logic
… by Priest of finding sound and complete labeled tableaux for systems of conditional logic from Lewis' <strong>V</strong>-family. To develop these tableaux, I draw on previous work on labeled tableaux for modal and conditional logic; errors and shortcomings in recent work on this problem are …

Combinatorics in Schubert varieties and Specht modules
… diagrams. We also define new class of toric tableaux of certain shapes, and conjecture the generating function of the tableaux is the Frobenius character of the corresponding Specht module. For a toric ribbon diagram, this is consistent with the previous conjecture. We also show that our …
