Shuffle algebras, lattice paths and quantum toroidal
Alexandr Garbali, Andrei Neguţ
We describe and compute various families of commuting elements of the matrix shuffle algebra of type , which is expected to be isomorphic to quantum toroidal $…

Rational symmetric functions from the Izergin-Korepin 19-vertex model
Alexandr Garbali, Weiying Guo, Michael Wheeler
Starting from the Izergin-Korepin 19-vertex model in the quadrant, we introduce two families of rational multivariate functions and ; these are in direct analogy with fu…

Modified Macdonald polynomials and integrability
Alexandr Garbali, Michael Wheeler
We derive combinatorial formulae for the modified Macdonald polynomial using coloured paths on a square lattice with quasi-cylindrical boundary conditions. The derivat…
