K-theoretic Schubert calculus for OG.n; 2nC 1/ and jeu de taquin for shifted increasing tableaux

چکیده

We present a proof of a Littlewood–Richardson rule for the K-theory of odd orthogonal Grassmannians OG.n; 2n C 1/, as conjectured by Thomas–Yong (2009). Specifically, we prove that rectification using the jeu de taquin for increasing shifted tableaux introduced there, is well-defined and gives rise to an associative product. Recently, Buch–Ravikumar (2012) proved a Pieri rule for OG.n; 2nC1/ that confirms a special case of the conjecture. Together, these results imply the aforementioned conjecture.

A Jeu De Taquin Theory for Increasing Tableaux, with Applications to K-theoretic Schubert Calculus

We introduce a theory of jeu de taquin for increasing tableaux, extending fundamental work of [Schützenberger ’77] for standard Young tableaux. We apply this to give a new combinatorial rule for the K-theory Schubert calculus of Grassmannians via K-theoretic jeu de taquin, providing an alternative to the rules of [Buch ’02] and others. This rule naturally generalizes to give a conjectural root-...

K-theory of Minuscule Varieties

Based on Thomas and Yong’s K-theoretic jeu de taquin algorithm, we prove a uniform Littlewood-Richardson rule for the K-theoretic Schubert structure constants of all minuscule homogeneous spaces. Our formula is new in all types. For the main examples of Grassmannians of type A and maximal orthogonal Grassmannians it has the advantage that the tableaux to be counted can be recognized without ref...

Promotion of Increasing Tableaux: Frames and Homomesies

A key fact about M.-P. Schützenberger’s (1972) promotion operator on rectangular standard Young tableaux is that iterating promotion once per entry recovers the original tableau. For tableaux with strictly increasing rows and columns, H. Thomas and A. Yong (2009) introduced a theory of K-jeu de taquin with applications to K-theoretic Schubert calculus. The author (2014) studied a K-promotion op...

Monodromy and K-theory of Schubert Curves via Generalized Jeu de Taquin

Schubert curves are the spaces of solutions to certain one-dimensional Schubert problems involving žags osculating the rational normal curve. e real locus of a Schubert curve is known to be a natural covering space of RP1, so its real geometry is fully characterized by the monodromy of the cover. It is also possible, using K-theoretic Schubert calculus, to relate the real locus to the overall (...

Shifted tableaux, schur Q-functions, and a conjecture of R. Stanley

We present an analog of the Robinson-Schensted correspondence that applies to shifted Young tableaux and is considerably simpler than the one proposed in [B. E. Sagan, J. Combin. Theory Ser. A 27 (1979), l&18]. In addition, this algorithm enjoys many of the important properties of the original Robinson-Schensted map including an interpretation of row lengths in terms of k-increasing sequences, ...
