Quantum K--theory of Grassmannians from a Yang-Baxter algebra
Vassily Gorbounov, Christian Korff, Leonardo C. Mihalcea
In an earlier paper, two of the authors defined a -vertex Yang-Baxter algebra (a Hopf algebra) which acts on the sum of the equivariant quantum K-rings of Grassmannians $\mathrm…
Cylindric Hecke characters and Gromov-Witten invariants via the asymmetric six-vertex model
Christian Korff
We construct a family of infinite-dimensional positive sub-coalgebras within the Grothendieck ring of Hecke algebras, when viewed as a Hopf algebra with respect to the induction an…
Cylindric symmetric functions and positivity
Christian Korff, David Palazzo
We introduce new families of cylindric symmetric functions as subcoalgebras in the ring of symmetric functions (viewed as a Hopf algebra) which have non-negative structure cons…
Yang-Baxter algebras as convolution algebras: The Grassmannian case
Vassily Gorbounov, Christian Korff, Catharina Stroppel
We present a simple but explicit example of a recent development which connects quantum integrable models with Schubert calculus: there is a purely geometric construction of soluti…
Cylindric Reverse Plane Partitions and 2D TQFT
Christian Korff, David Palazzo
The ring of symmetric functions carries the structure of a Hopf algebra. When computing the coproduct of complete symmetric functions one arrives at weighted sums over revers…
Dimers, crystals and quantum Kostka numbers
Christian Korff
We relate the counting of honeycomb dimer configurations on the cylinder to the counting of certain vertices in Kirillov-Reshetikhin crystal graphs. We show that these dimer config…
