Time-dependent Lagrangians invariant by a vector field

数学物理 2015-12-15 v2 math.MP

摘要

We study the reduction of non-autonomous regular Lagrangian systems by symmetries, which are generated by vector fields associated with connections in the configuration bundle of the system Q×Q\times\real\to\real. These kind of symmetries generalize the idea of ``time-invariance'' (which corresponds to taking the trivial connection in the above trivial bundle).
