Self-Dual Symmetric Polynomials and Conformal Partitions
نویسنده
چکیده
A conformal partition function Pm n (s), which arose in the theory of Diophantine equations supplemented with additional restrictions, is concerned with self-dual symmetric polynomials – reciprocal R {m} Sn and skew-reciprocal S {m} Sn algebraic polynomials based on the polynomial invariants of the symmetric group Sn. These polynomials form an infinite commutative semigroup. Real solutions λn(xi) of corresponding algebraic Eqns have many important properties: homogeneity of 1-st order, duality upon the action of the conformal group W, inverting both function λn and the variables xi, compatibility with trivial solution, etc. Making use of the relationship between Gaussian generating function for conformal partitions and Molien generating function for usual restricted partitions we derived the analytic expressions for Pm n (s). The unimodality indices for the reciprocal and skew-reciprocal equations were found. The existence of algebraic functions λn(xi) invariant upon the action of both the finite group G ⊂ Sn and conformal group W is discussed.

Refined Dual Stable Grothendieck Polynomials and Generalized Bender-Knuth Involutions
The dual stable Grothendieck polynomials are a deformation of the Schur functions, originating in the study of the K-theory of the Grassmannian. We generalize these polynomials by introducing a countable family of additional parameters, and we prove that this generalization still defines symmetric functions. For this fact, we give two self-contained proofs, one of which constructs a family of i...
متن کاملMurphy Operators and the Centre of the Iwahori-Hecke Algebras of Type A
In this paper we introduce a family of polynomials indexed by pairs of partitions and show that if these polynomials are self-orthogonal then the centre of the Iwahori-Hecke algebra of the symmetric group is precisely the set of symmetric polynomials in the Murphy operators.

متن کاملNon-crossing partitions for classical reflection groups
We introduce analogues of the lattice of non-crossing set partitions for the classical reeection groups of type B and D. The type B analogues ((rst considered by Montenegro in a diierent guise) turn out to be as well-behaved as the original non-crossing set partitions, and the type D analogues almost as well-behaved. In both cases, they are EL-labellable ranked lattices with symmetric chain dec...
متن کاملOn hyperbolicity cones associated with elementary symmetric polynomials
Elementary symmetric polynomials can be thought of as derivative polynomials of En(x) = ∏ i=1,...,n xi. Their associated hyperbolicity cones give a natural sequence of relaxations for R+. We establish a recursive structure for these cones, namely, that the coordinate projections of these cones are themselves hyperbolicity cones associated with elementary symmetric polynomials. As a consequence ...
