TECHNIQUES OF HIGHER ORDER OSCULATOR BUNDLE IN GENERALIZED GAUGE THEORY Gheorghe Munteanu 1991 Math. Subject Classification: 53C80. Abstract: Given a certain state of a mechanical system, the object of many physical theories is to determine the way in which that state changes in time. The evolution of the system is usually gouverned by Euler-Lagrange equations and this evolution must look the same in every coordinate system. In gauge theories, in addition to the invariance under changes of coordinates, is involved another invariance, under the so called gauge transformations. In classical gauge theory the physical system is represented by sections in an associate bundle, and is required to be invariant with respect to this gauge change. In this paper we shall generalize the concept of gauge transformation of one system developed in a $k$-osculator bundle ([7],[8]), the associate bundle of the bundle of $k$-frames. The geometrical notion of gauge derivatives is studied and the $k$-order Einstein Yang-Mills equations are obtained. A general class of gauge invariant Lagrangians is given.
