Abstract
The Euler–Lagrange equations of recentlyintroduced chiral action principles are discussed usingLie algebra-valued differential forms. Symmetries of theequations and the chiral description of Einstein's vacuum equations are presented. A class ofLagrangians which contains the chiral formulations isexhibited.
