Zusammenfassung
Just like AdS spacetimes, Lifshitz spacetimes require counterterms in order
to make the on-shell value of the bulk action finite. We study these
counterterms using the Hamilton-Jacobi method. Rather than imposing boundary
conditions from the start, we will derive suitable boundary conditions by
requiring that divergences can be canceled using only local counterterms. We
will demonstrate in examples that this procedure indeed leads to a finite bulk
action while at the same time it determines the asymptotic behavior of the
fields. This puts more substance to the belief that Lifshitz spacetimes are
dual to well-behaved field theories. As a byproduct, we will find the analogue
of the conformal anomaly for Lifshitz spacetimes.
