Mixed volumes of hypersimplices, root systems and shifted young tableaux
… with 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 …

The Koszul dual to n-Lie, n-Com algebras, and Young tableaux
… we construct combinatorial objects, called Young $n$-trees, 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 …

Rectification of Composition Tableaux
… the rectification of a reverse semi-standard Young tableau. 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.

Branching from K to M for split classical groups
… A, one inductive and one related to semistandard Young tableaux. The results extend to branching from Ke to M Ke for the real split reductive groups of type Bn and Dn.

Pattern avoidance for alternating permutations and reading words of tableaux
… a monotone 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 …

Phase structure and symmetry breaking in SU(N) ferromagnets
… φέρουν τα άτομα. Oι φάσεις χαρακτηρίζονται από Young Tableaux, ειδικότερα δε σε χαμηλές θερμοκρασίες αντιστοιχούν σε αναπαραστάσεις της SU(N) με σταθερό αριθμό κουτιών που μεγιστοποιούν τον τετραγωνικό Casimir. Οι μαγνητισμένες φάσεις σπάνε αυθόρμητα τη συμμετρία SU(N) των σιδηρομαγνητών, ενώ …

Much ado about nothing: The superconformal index and Hilbert series of three dimensional N =4 vacua
We study a quantum mechanical $\sigma$-model whose target space is a hyperKähler cone. As shown by Singleton, [184], such a theory has superconformal invariance under the algebra $\mathfrak{osp}(4^*|4)$. One can formally define a superconformal index that counts the short representations of the …
