After giving a detailed introduction to Janet bases and Thomas decomposition, the problem of finding an implicit description of certain sets of analytic functions in terms of differential equations is addressed. Effective methods of varying generality are developed to solve the differential elimination problems that arise in this context. In particular, it is demonstrated how the symbolic solution of partial differential equations profits from the study of the implicitization problem. For instance, certain families of exact solutions of the Navier-Stokes equations can be computedDifferential equations, PartialEliminationPrinted edition:9783319114446.b1425840717-11-1615-07-16991002946249707536LE013 12H ROB11 (2014)12013000293608le013pE46.79-l- 01010.i1578751517-11-16Formal algorithmic elimination for PDEs1388028UNISALENTOle01315-07-16ma -engsz 0000876nam0-2200301 --450 991083998040332120240403173358.088-343-0388-1IT97-5320240403d1996----kmuy0itay5050 baitaIT 001yy<<La >>via analogicaVirgilio MelchiorreMilanoVita e pensiero1996XVI, 322 p.22 cmPubblicazioni del Centro di ricerche di metafisica.
