That act set in motion the remarkable saga of one of the world's most influential crops--one that would transform the future of Africa and of the Atlantic world. The recent spread of maize has been alarmingly fast, with implications largely overlooked by the media and policymakers. McCann's compelling history offers insight into the profound influence of a single crop on African culture, health, technological innovation, and the future of the world's food supply.CornAfricaHistoryGrainAfricaHistoryCornHistory.GrainHistory.633.15096NW 2570rvkMcCann James1950-896977MiAaPQMiAaPQMiAaPQBOOK996247851503316Maize and grace2363466UNISA03271nam0 2200589 i 450 VAN0006033520250428090813.371978-35-402-4200-020070711d2005 |0itac50 baengDE|||| |||||Hypoelliptic estimates and spectral theory for Fokker-Planck operators and Witten LaplaciansBernard Helffer, Francis NierBerlinSpringer2005X, 209 p.24 cmPubblicazione disponibile anche in formato elettronico001VAN001022502001 Lecture notes in mathematics210 Berlin [etc.]Springer1862VAN00234513Hypoelliptic Estimates and Spectral Theory for Fokker-Planck Operators and Witten Laplacians102656335H10Hypoelliptic equations [MSC 2020]VANC021221MF35H20Subelliptic equations [MSC 2020]VANC021222MF35P05General topics in linear spectral theory for PDEs [MSC 2020]VANC021223MF35P15Estimation of eigenvalues in context of PDEs [MSC 2020]VANC021224MF58J10Differential complexes ; elliptic complexes [MSC 2020]VANC022977MF58J50Spectral problems; spectral geometry; scattering theory on manifolds [MSC 2020]VANC021225MF58K65Topological invariants on manifolds [MSC 2020]VANC029584MF81Q10Selfadjoint operator theory in quantum theory, including spectral analysis [MSC 2020]VANC020683MF81Q20Semiclassical techniques including WKB and Maslov methods applied to problems in quantum theory [MSC 2020]VANC021228MF82C05Classical dynamic and nonequilibrium statistical mechanics (general) [MSC 2020]VANC021229MF82C31Stochastic methods (Fokker-Planck, Langevin, etc.) applied to problems in time-dependent statistical mechanics [MSC 2020]VANC020047MF82C40Kinetic theory of gases in time-dependent statistical mechanics [MSC 2020]VANC023377MFCalculusKW:KCompactnessKW:KCompactness criteriaKW:KEigenvaluesKW:KFokker-Planck operatorsKW:KHypoellipticityKW:KMaximumKW:KPartial Differential EquationsKW:KReturn to equilibriumKW:KWitten LaplaciansKW:KBerlinVANL000066HelfferBernardVANV04380252445NierFrancisVANV047653497842Springer <editore>VANV108073650ITSOL20250502RICA/sebina/repository/catalogazione/documenti/ID 60335.pdfID 60335.pdfhttps://doi.org/10.1007/b104762https://doi.org/10.1007/b104762BIBLIOTECA DEL DIPARTIMENTO DI MATEMATICA E FISICAIT-CE0120VAN08VAN00060335BIBLIOTECA DEL DIPARTIMENTO DI MATEMATICA E FISICA08PREST 35-XX 1855 08 7641 I 20070711 Hypoelliptic estimates and spectral theory for Fokker-Planck operators and Witten Laplacians1026563UNICAMPANIA
