Phys. Rev. D 34, 424–433 (1986)Symmetry and variational methods in higher-dimensional theoriesReceived 18 February 1986; published in the issue dated 15 July 1986 The problem of imposing symmetry on variational principles for higher-dimensional theories is illustrated by considering spatially homogeneous solutions of Kaluza-Klein theories. Various implications of the group-theoretical nature of this specific situation are addressed. © 1986 The American Physical Society URL:
