Alternating sign matrices and totally symmetric plane partitions
Florian Aigner, Ilse Fischer, Matjaž Konvalinka +2
We study the Schur polynomial expansion of a family of symmetric polynomials related to the refined enumeration of alternating sign matrices with respect to their inversion number,…
The permutahedral variety, mixed Eulerian numbers, and principal specializations of Schubert polynomials
Philippe Nadeau, Vasu Tewari
We compute the expansion of the cohomology class of the permutahedral variety in the basis of Schubert classes. The resulting structure constants are expressed as a sum of \e…
Trimming the permutahedron to extend the parking space
Matjaž Konvalinka, Robin Sulzgruber, Vasu Tewari
Berget and Rhoades asked whether the permutation representation obtained by the action of on parking functions of length can be extended to a permutation action of…
Some natural extensions of the parking space
Matjaž Konvalinka, Vasu Tewari
We construct a family of modules indexed by with the property that upon restriction to they recover the classical parking function representatio…
