Crystals and p-adic Integration --Bibliography --Notation --IndexWeyl group multiple Dirichlet series are generalizations of the Riemann zeta function. Like the Riemann zeta function, they are Dirichlet series with analytic continuation and functional equations, having applications to analytic number theory. By contrast, these Weyl group multiple Dirichlet series may be functions of several complex variables and their groups of functional equations may be arbitrary finite Weyl groups. Furthermore, their coefficients are multiplicative up to roots of unity, generalizing the notion of Euler products. This book proves foundational results about these series and develops their combinatorics. These interesting functions may be described as Whittaker coefficients of Eisenstein series on metaplectic groups, but this characterization doesn't readily lead to an explicit description of the coefficients. The coefficients may be expressed as sums over Kashiwara crystals, which are combinatorial analogs of characters of irreducible representations of Lie groups. For Cartan Type A, there are two distinguished descriptions, and if these are known to be equal, the analytic properties of the Dirichlet series follow. Proving the equality of the two combinatorial definitions of the Weyl group multiple Dirichlet series requires the comparison of two sums of products of Gauss sums over lattice points in polytopes. Through a series of surprising combinatorial reductions, this is accomplished. The book includes expository material about crystals, deformations of the Weyl character formula, and the Yang-Baxter equation.Annals of mathematics studies ;no. 175.Dirichlet seriesWeyl groupsBZL pattern.Class I.Eisenstein series.Euler product.Gauss sum.Gelfand-Tsetlin pattern.Kashiwara operator.Kashiwara's crystal.Knowability Lemma.Kostant partition function.Riemann zeta function.Schur polynomial.Schützenberger involution.Snake Lemma.Statement A.Statement B.Statement C.Statement D.Statement E.Statement F.Statement G.Tokuyama's Theorem.Weyl character formula.Weyl denominator.Weyl group multiple Dirichlet series.Weyl vector.Whittaker coefficient.Whittaker function.Yang-Baxter equation.Yang–Baxter equation.accordion.adele group.affine linear transformation.analytic continuation.analytic number theory.archimedean place.basis vector.bijection.bookkeeping.box-circle duality.boxing.canonical indexings.cardinality.cartoon.circling.class.combinatorial identity.concurrence.critical resonance.crystal base.crystal graph.crystal.divisibility condition.double sum.episode.equivalence relation.f-packet.free abelian group.functional equation.generating function.global field.ice-type model.inclusion-exclusion.indexing.involution.isomorphism.knowability.maximality.nodal signature.nonarchimedean local field.noncritical resonance.nonzero contribution.p-adic group.p-adic integral.p-adic integration.partition function.polynomial.preaccordion.prototype.reduced root system.representation theory.residue class field.resonance.resotope.row sums.row transfer matrix.short pattern.six-vertex model.snakes.statistical mechanics.subsignature.tableaux.type.Γ-equivalence class.Γ-swap.Dirichlet series.Weyl groups.515/.243Brubaker Ben1976-1468330Bump Daniel1952-56694Friedberg Solomon1958-1468331MiAaPQMiAaPQMiAaPQBOOK9910789812403321Weyl group multiple Dirichlet3679458UNINA
