In this paper we study the perturbation theory of recently proposed Regularized Lovelock Gravity (Glavan and Lin, 2020), on curved Friedmann–Lemaître–Robertson–Walker (FLRW) space–time. We provide first order equations both in scalar tensor sector presence an additional minimally coupled field. A general expression for velocity gravitational waves at generic is inferred. Moreover, apply results...

In this study we present evolving wormhole configurations in third-order {Lovelock} gravity and investigate the possibility that these solutions satisfy energy conditions. Using a generalized Friedmann-Robertson-Walker spacetime, derive geometries by considering constraint on Ricci scalar. standard cosmological models, scalar is independent of radial coordinate $r$ only function time. We use pr...

We explore wormhole geometry in spiral galaxies under the third order Lovelock gravity. Using cubic spline interpolation technique, we find rotational velocity of test particles halo region our galaxy from observed values radial distances and velocities. Taking this value velocity, are able to show that it is possible present a mathematical model regarding viable existence wormholes galactic Mi...
