Web Theory And Related Topics
ISBN: 9789810246044 / Angielski / Twarda / 2001 / 244 str. Termin realizacji zamówienia: ok. 22 dni roboczych. This book provides an overview of recent developments in web theory. Webs (i.e. families of foliations in general position) appear in many different fields of mathematics (differential geometry, algebraic geometry, differential equations, symplectic geometry, etc.) and physics (mechanics, geometrical optics, etc.). After giving a survey on webs in differential geometry and algebraic geometry, the book presents new results on partial differential equations, integrable systems, holomorphic dynamics and nonlinear optics obtained through web theory.

Variational Principles for Second-Order Differential Equations, Application of the Spencer Theory of
ISBN: 9789810237349 / Angielski / Twarda / 2000 / 228 str. Termin realizacji zamówienia: ok. 22 dni roboczych. The inverse problem of the calculus of variations was first studied by Helmholtz in 1887 and it is entirely solved for the differential operators, but only a few results are known in the more general case of differential equations. This book looks at second-order differential equations and asks if they can be written as Euler-Lagrangian equations. If the equations are quadratic, the problem reduces to the characterization of the connections which are Levi-Civita for some Riemann metric.To solve the inverse problem, the authors use the formal integrability theory of overdetermined partial...
