A Unimodality Identity for a Schur Function
نویسندگان
چکیده
It is well known that the principal specialization of the Schur function, sλ(1, q, . . . , q ), is a unimodal polynomial. A brief representation theoretic proof consists in identifying sλ(1, q, . . . , q ) as the character of a homogeneous polynomial representation of GL(2,C) evaluated at diag(1, q), see [3, p. 67]. Recently O’Hara gave a combinatorial proof [4] of the unimodality of the Gaussian coef-

Unimodality of Eulerian quasisymmetric functions
We prove two conjectures of Shareshian and Wachs about Eulerian quasisymmetric functions and polynomials. The first states that the cycle type Eulerian quasisymmetric function Qλ,j is Schur-positive, and moreover that the sequence Qλ,j as j varies is Schur-unimodal. The second conjecture, which we prove using the first, states that the cycle type (q, p)-Eulerian polynomial A λ (q, p, q −1t) is ...
متن کاملOn discrete a-unimodal and a-monotone distributions
Unimodality is one of the building structures of distributions that like skewness, kurtosis and symmetry is visible in the shape of a function. Comparing two different distributions, can be a very difficult task. But if both the distributions are of the same types, for example both are unimodal, for comparison we may just compare the modes, dispersions and skewness. So, the concept of unimodali...
متن کاملUnimodality of generalized Gaussian coefficients
A combinatorial proof of the unimodality of the generalized q-Gaussian coefficients [ N λ ] q based on the explicit formula for Kostka-Foulkes polynomials is given. 1. Let us mention that the proof of the unimodality of the generalized Gaussian coefficients based on theoretic-representation considerations was given by E.B. Dynkin [1] (see also [2], [10], [11]). Recently K.O’Hara [6] gave a cons...
متن کاملBijective Proofs for Schur Function Identities
In [4], Gurevich, Pyatov and Saponov stated an expansion for the product of two Schur functions and gave a proof based on the Plücker relations. Here we show that this identity is in fact a special case of a quite general Schur function identity, which was stated and proved in [1, Lemma 16]. In [1], it was used to prove bijectively Dodgson’s condensation formula and the Plücker relations, but w...
