For a partition [Formula: see text] and prime text], we prove necessary sufficient condition for there to exist composition such that can be obtained from after rearrangement no partial sums of are divisible by text]. To demonstrate why interested in the question, compute some signed text]-Kostka numbers.
We identify “spurious” states in meson-baryon scattering, those that appear in QCD for Nc > 3 but decouple for Nc = 3. The key observation is that the relevant flavor SU(3) Clebsch-Gordan coefficients contain factors of 1−3/Nc. We show that this method works even if SU(3) is badly broken. We also observe that resonant scattering poles lying outside naive quark model multiplets are not necessari...
We report on the 2005 AIM workshop “Generalized Kostka Polynomials“, which gathered 20 researchers in the active area of q, t-analogues of symmetric functions. Our goal is to present a typical use-case of the open source package MuPAD-Combinat in a research environment.
We show that the specialization of nonsymmetric Macdonald polynomials at t = 0 are, up to multiplication by a simple factor, characters of Demazure modules for ŝl(n). This connection furnishes Lie-theoretic proofs of the nonnegativity and monotonicity of Kostka polynomials.
In this paper we study an approximation of tensor product of irreducible integrable sl2 representations by infinite fusion products. This gives an approximation of the corresponding coset theories. As an application we represent characters of spaces of these theories as limits of certain restricted Kostka polynomials. This leads to the bosonic (which is known) and fermionic (which is new) formu...
Kostka T, Furgal W, Gawroński W, et al. Br J Sports Med (2011). doi:10.1136/bjsports-2011-090043 1 of 4 Systematic physical activity is a necessary element of normal development of a young human body.1 2 From early childhood, people should participate in sports and recreational activities involving movement. However, organised and systematic learning of a given form of motor activity (physical ...
We give several equivalent combinatorial descriptions of the space of states for the box-ball systems, and connect certain partition functions for these models with the q-weight multiplicities of the tensor product of the fundamental representations of the Lie algebra gl(n). As an application, we give an elementary proof of the special case t = 1 of the Haglund–Haiman–Loehr formula. Also, we pr...
