Skew quantum Murnaghan-Nakayama rule [PDF]

open access: yes, 2011
In this paper, we extend recent results of Assaf and McNamara on skew Pieri rule and skew Murnaghan-Nakayama rule to a more general identity, which gives an elegant expansion of the product of a skew Schur function with a quantum power sum function in ...

A Pieri rule for Hermitian symmetric pairs I [PDF]

open access: yesPacific Journal of Mathematics, 2004
Let \((G,K)\) be a Hermitian symmetric pair, and let \(\mathfrak g\supset\mathfrak k\) denote the corresponding complexified Lie algebra. Then \(\mathfrak k = \mathbb C H\oplus [\mathfrak k,\mathfrak k]\), where \(\text{ad}\,H\) has the eigenvalues \(-1,0,1\) on \(\mathfrak g\). Let \(\mathfrak g = \mathfrak p^-\oplus\mathfrak k\oplus\mathfrak p^+\) be

Gromov-Witten invariants on Grassmannians [PDF]

open access: yes, 2003
We prove that any three-point genus zero Gromov-Witten invariant on a type A Grassmannian is equal to a classical intersection number on a two-step flag variety. We also give symplectic and orthogonal analogues of this result; in these cases the two-step

The Pieri Rule for GL n Over Finite Fields [PDF]

open access: yes, 2020
The Pieri rule gives an explicit formula for the decomposition of the tensor product of irreducible representation of the complex general linear group GL(n,C) with a symmetric power of the standard representation on C^n. It is an important and long understood special case of the Littlewood-Richardson rule for decomposing general tensor products of ...

Comment on "Density and Spin response of a strongly-interacting Fermi gas in the attractive and quasi-repulsive regime" [PDF]

open access: yes, 2012
This is a comment on Phys. Rev. Lett. 108, 080401 (2012) by Palestini et al. We pointed out that the diagrammatic method in that article violates gauge invariance.

The Compressibility in Strongly Correlated Superconductors and Superfluids: From BCS to BEC [PDF]

open access: yes, 2013
We present a theoretical study of the compressibility, $\kappa$, in a Fermi gas with attractive contact interactions, providing predictions for the strongly-attractive regime and the superfluid phase.

Bernstein operators for universal characters and symplectic universal characters

open access: yesNuclear Physics B
This paper focuses on the construction of the Bernstein operators for universal characters and symplectic universal characters. By carrying out the action of a series of Bernstein operators on the constant function 1, universal characters and symplectic ...

An Orthosymplectic Pieri Rule

open access: yesThe Electronic Journal of Combinatorics, 2018
The classical Pieri formula gives a combinatorial rule for decomposing the product of a Schur function and a complete homogeneous symmetric polynomial as a linear combination of Schur functions with integer coefficients. We give a Pieri rule for describing the product of an orthosymplectic character and an orthosymplectic character arising from a one ...
