New canonical analysis for higher order topologically massive gravity

A detailed Gitman-Lyakhovich-Tyutin analysis for higher-order topologically massive gravity is performed. The full structure of the constraints, the counting of physical degrees of freedom, and the Dirac algebra among the constraints are reported. Moreover, our analysis presents a new structure into the constraints and we compare our results with those reported in the literature where a standard Ostrogradski framework was developed.

Automated summary

A detailed analysis of higher-order topologically massive gravity was conducted, reporting the full structure of constraints, counting of physical degrees of freedom, and the Dirac algebra among the constraints. The analysis presented a new structure within the constraints and compared the results with those in the literature developed under a standard Ostrogradski framework.
