Effective delta sources and Newtonian limit in nonlocal gravity
Thomas M. Sangy, Nicolò BurzillÃ, Breno L. Giacchini +1
We investigate the Newtonian limit of a class of nonlocal gravity models with exponential form factors . Our main goal is to identify simi…

On the total derivative divergence for a nonminimal vector operator
Thomas M. Sangy, Tibério de Paula Netto, Tibério de Paula Netto +1
We report on the calculation of the total derivative term in the divergence of vacuum effective action for the nonminimal vector field operator in a curved space backgroun…

On effective models of regular black holes inspired by higher-derivative and nonlocal gravity
Tibério de Paula Netto, Breno L. Giacchini, Nicolò Burzillà +1
In this work we study static spherically symmetric solutions of effective field equations related to local and nonlocal higher-derivative gravity models, based on their associated…
