In this article, we review several classes of polytopes that do have unimodular triangulations and constructions that preserve their existence. We include, in particular, the first effective proof of the classical result by Knudsen-Mumford-Waterman stating that every lattice polytope has a dilation that admits a unimodular triangulation. Our proof yields an explicit (although doubly exponential) bound for the dilation factor"--Provided by publisher.Memoirs of the American Mathematical Society Convex polytopesTriangularization (Mathematics)Combinatorial geometryConvex and discrete geometry -- Polytopes and polyhedra -- Lattice polytopes (including relations with commutative algebra and algebraic geometry)mscConvex and discrete geometry -- Polytopes and polyhedra -- $n$-dimensional polytopesmscCommutative algebra -- Arithmetic rings and other special rings -- Polynomial rings and ideals; rings of integer-valued polynomialsmscConvex polytopes.Triangularization (Mathematics)Combinatorial geometry.Convex and discrete geometry -- Polytopes and polyhedra -- Lattice polytopes (including relations with commutative algebra and algebraic geometry).Convex and discrete geometry -- Polytopes and polyhedra -- $n$-dimensional polytopes.Commutative algebra -- Arithmetic rings and other special rings -- Polynomial rings and ideals; rings of integer-valued polynomials.516/.0852B2052B1113F20mscHaase Christian288859Paffenholz Andreas1801796Piechnik Lindsay C1801797MiAaPQMiAaPQMiAaPQBOOK9910970826703321Existence of Unimodular Triangulations-Positive Results4347192UNINA04810oam 22011774 450 991095678870332120250426110835.0978661382255097814623770601462377068978145199643214519964389781282588769128258876197814519082441451908245(CKB)3360000000443290(EBL)3014341(SSID)ssj0000940740(PQKBManifestationID)11532936(PQKBTitleCode)TC0000940740(PQKBWorkID)10955959(PQKB)10425580(OCoLC)440837441(MiAaPQ)EBC3014341(IMF)WPIEE2006028(IMF)WPIEA2006028WPIEA2006028(EXLCZ)99336000000044329020020129d2006 uf 0engur|n|---|||||txtccrZimbabwe's Export Performance : The Impact of the Parallel Market and Governance Factors /Sònia Muñoz1st ed.Washington, D.C. :International Monetary Fund,2006.1 online resource (17 p.)IMF Working Papers"January 2006."9781451862881 1451862881 Includes bibliographical references (p. 14-15).""Contents""; ""I.

Description of Sources and Transformation""; ""REFERENCES""This paper analyzes Zimbabwe's export performance in recent years and identifies the factors that could improve export performance, from both a quantitative and qualitative perspective. Improving export performance is critical to a turnaround in Zimbabwe's economic situation. The growth rate of total exports declined dramatically in the early 2000s, following a large real appreciation of the currency and the introduction of the fast-track land reform program. An important finding of the paper is that policies that reduce (eliminate) the parallel market premium and lower ethnic tensions would be key to promoting export growth.IMF Working Papers; Working Paper ;No. 2006/028ExportsZimbabweEconometric modelsInternational tradeEconometric modelsCurrencyimfDevelopment Planning and Policy: Trade PolicyimfExchange ratesimfExport performanceimfExports and ImportsimfExportsimfFactor MovementimfForeign Exchange PolicyimfForeign ExchangeimfForeign exchangeimfFormal and Informal SectorsimfInstitutional ArrangementsimfInternational economicsimfInternational tradeimfModels of Trade with Imperfect Competition and Scale EconomiesimfMultiple currency practicesimfMultiple or Simultaneous Equation Models: Models with Panel DataimfNatural Resources and Domestic and International ConflictsimfReal exchange ratesimfShadow EconomyimfTrade: GeneralimfZimbabweimfExportsEconometric models.International tradeEconometric models.CurrencyDevelopment Planning and Policy: Trade PolicyExchange ratesExport performanceExports and ImportsExportsFactor MovementForeign Exchange PolicyForeign ExchangeForeign exchangeFormal and Informal SectorsInstitutional ArrangementsInternational economicsInternational tradeModels of Trade with Imperfect Competition and Scale EconomiesMultiple currency practicesMultiple or Simultaneous Equation Models: Models with Panel DataNatural Resources and Domestic and International ConflictsReal exchange ratesShadow EconomyTrade: GeneralMuñoz Sònia1815672International Monetary Fund.African Dept.DcWaIMFBOOK9910956788703321Zimbabwe's Export Performance4372052UNINA
