In our previous paper, we gave a presentation of the torus-equivariant quantum K-theory ring $QK_{H}(Fl_{n+1})$ of the (full) flag manifold $Fl_{n+1}$ of type $A_{n}$ as a quotient of a polynomial ring by an explicit ideal.

Free fermionic probability theory and k-theoretic schubert calculus
For each of the four particle processes given by Dieker and Warren, we show the n-step transition kernels are given by the (dual) (weak) refined symmetric Grothendieck functions up to a simple overall factor. We do so by encoding the particle dynamics as

Positively multiplicative graphs and homology rings of affine Grassmannians
Let \(\mathfrak{g}\) be an untwisted affine Lie algebra with associated Weyl group \(W_a\) and let \(W\) be the Weyl group of the corresponding simple Lie algebra.

The quasisymmetric flag variety: A toric complex on noncrossing partitions
We develop the geometric theory of equivariant quasisymmetry via a new “quasisymmetric flag variety.” This is a toric complex in the flag variety whose fixed point set is the set of (algebraic) noncrossing partitions, and whose cohomology ring is the ...

Diagonal operators, \(q\)-Whittaker functions and rook theory
We discuss the problem posed by Bender, Coley, Robbins and Rumsey of enumerating the number of subspaces which have a given profile with respect to a linear operator over the finite field \(\mathbb{F}_q\).

Bounded Littlewood identity related to alternating sign matrices
An identity that is reminiscent of the Littlewood identity plays a fundamental role in recent proofs of the facts that alternating sign triangles are equinumerous with totally symmetric self-complementary plane partitions and that alternating sign ...

Towards a Theory of Negative Dependence
: The FKG theorem says that the POSITIVE LATTICE CONDITION, an easily checkable hypothesis which holds for many natural families of events, implies POSITIVE ASSOCIATION, a very useful property.

Plethysms, replicated Schur functions and series, with applications to vertex operators
Specializations of Schur functions are exploited to define and evaluate the Schur functions sλ[αX] and plethysms sλ[αsν(X))] for any α—integer, real or complex.
