Abstract:
Path and path deviation equations for neutral, charged, spinning and spinning charged test particles, using a modified Bazanski Lagrangian, are derived. We extend this approach to strings and branes. We show how the Bazanski Lagrangian for charged point particles and charged branes arises la Kaluza-Klein from the Bazanski Lagrangian in 5-dimensions. 2012 Versita Warsaw and Springer-Verlag Wien.
