Adiabatic invariants and Mixmaster catastrophes
S. Cotsakis, R. L. Lemmer, P. G. L. Leach
We present a rigorous analysis of the role and uses of the adiabatic invariant in the Mixmaster dynamical system. We propose a new invariant for the global dynamics which in some r…

Variational and conformal structure of nonlinear metric-connection gravitational lagrangians
S. Cotsakis, J. Miritzis, L. Querella
We examine the variational and conformal structures of higher order theories of gravity which are derived from a metric-connection Lagrangian that is an arbitrary function of the c…
