books.google.com - This book presents in a unified way modern geometric methods in analytical mechanics based on the application of fibre bundles, jet manifold formalism and the related concept of connection. Non-relativistic mechanics is seen as a particular field theory over a one-dimensional base. In fact, the concept...http://books.google.com/books/about/Gauge_Mechanicas.html?id=-N6F44hlnhgC&utm_source=gb-gplus-shareGauge Mechanicas
