Finite dimesional Hamiltonian formalism for gauge and field theories
We discuss in this paper the canonical structure of classical field theory in
finite dimensions within the {\it{pataplectic}} Hamiltonian formulation, where
we put forward the role of Legendre correspondance. We define the generalized
Poisson -brackets which are the analogues of the Poisson bracket
on forms. We formulate the equations of motion of forms in terms of
-brackets. As illustration of our formalism we present three
examples: the interacting scalar fields, conformal string theory and the
electromagnetic field.Comment: 52 pages. In this paper we give a more general hamiltonian
formulation for a gauge and field theories, it's an extension of our previous
paper math-ph/000402
Foundations of mathematics and physics one century after Hilbert: new perspectives
This book explores the rich and deep interplay between mathematics and physics one century after David Hilbertâs works from 1891 to 1933, published by Springer in six volumes. The most prominent scientists in various domains of these disciplines contribute to this volume providing insight to their works, and analyzing the impact of the breakthrough and the perspectives of their own contributions. The result is a broad journey through the most recent developments in mathematical physics, such as string theory, quantum gravity, noncommutative geometry, twistor theory, Gauge and Quantum fields theories, just to mention a few. The reader, accompanied on this journey by some of the fathers of these theories, explores some far reaching interfaces where mathematics and theoretical physics interact profoundly and gets a broad and deep understanding of subjects which are at the core of recent developments in mathematical physics. The journey is not confined to the present state of the art, but sheds light on future developments of the field, highlighting a list of open problems. Graduate students and researchers working in physics, mathematics and mathematical physics will find this journey extremely fascinating. All those who want to benefit from a comprehensive description of all the latest advances in mathematics and mathematical physics, will find this book very useful too
Gravitation multisymplectique
Ce travail de thĂšse s'inscrit dans cadre de l'application de la GĂ©omĂ©trie DiffĂ©rentielle pour la RelativitĂ© GĂ©nĂ©rale, en particulier elle prĂ©sente l'approche de la GĂ©omĂ©trie Multisymplectique pour la formulation de plusieurs exemple de thĂ©orie de jauge, et de la thĂ©orie de gravitation. La GĂ©omĂ©trie Multisymplectique nous offre un cadre gĂ©omĂ©trique pour formuler la thĂ©orie classique des champs de maniĂšre indĂ©pendante des coordonnĂ©es, sur des espace-temps gĂ©nĂ©raux. L'idĂ©e clĂ© est de construire une description Hamiltonienne de la thĂ©orie des champs compatible avec les Principes de la relativitĂ© restreinte et gĂ©nĂ©rale, des thĂ©ories des cordes et plus gĂ©nĂ©ralement avec toute tentative de comprendre la gravitation. Lespace-temps Ă©merge de la dynamique elle-mĂȘme et il n'y a pas de sĂ©paration espace-temps/champs donnĂ©e a priori. n'y a pas de structure d'espace-temps donnĂ©e a priori. Les coordonnĂ©es d'espace-temps Ă©mergent de l'analyse des quantitĂ©s observables et de la dynamique.PARIS7-BibliothĂšque centrale (751132105) / SudocSudocFranceF
