Sommario/riassunto |
|
As democracy has swept the globe, the question of why some democracies succeed while others fail has remained a pressing concern. In this theoretically innovative, richly historical study, Michael Bernhard looks at the process by which new democracies choose their political institutions, showing how these fundamental choices shape democracy's survival. Offering a new analytical framework that maps the process by which basic political institu-tions emerge, Bernhard investigates four paradigmatic episodes of democracy in two countries: Germany during the Weimar period and after World War II, a |

Sommario/riassunto |
|
Investigating the correspondence between systems of partial differential equations and their analytic solutions using a formal approach, this monograph presents algorithms to determine the set of analytic solutions of such a system and conversely to find differential equations whose set of solutions coincides with a given parametrized set of analytic functions. 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 computed. |
