Tableau formulas for skew Grothendieck polynomials
Harry Tamvakis
An element of a Weyl group of classical type is skew if it is the left factor in a reduced factorization of a Grassmannian element. The skew Grothendieck polynomials are those whic…
Tableau formulas for skew Schubert polynomials
Harry Tamvakis
The skew Schubert polynomials are those which are indexed by skew elements of the Weyl group, in the sense of arXiv:0812.0639. We obtain tableau formulas for the double versions of…
The roots of mathematical thought
Harry Tamvakis
In this paper, I explore what mathematical research can tell us about ourselves, and our role in the world, using examples from my own experience. The paper is a sequel to my piece…
Degeneracy locus formulas for amenable Weyl group elements
Harry Tamvakis
We define a class of amenable Weyl group elements in the Lie types B, C, and D, which we propose as the analogues of vexillary permutations in these Lie types. Our amenable signed…
Theta and eta polynomials in geometry, Lie theory, and combinatorics
Harry Tamvakis
The classical Schur polynomials form a natural basis for the ring of symmetric polynomials, and have geometric significance since they represent the Schubert classes in the cohomol…
Schubert polynomials, theta and eta polynomials, and Weyl group invariants
Harry Tamvakis
We examine the relationship between the (double) Schubert polynomials of Billey-Haiman and Ikeda-Mihalcea-Naruse and the (double) theta and eta polynomials of Buch-Kresch-Tamvakis…
