Cosmological Hyperfluids, Torsion and Non-metricity
Damianos Iosifidis
We develop a novel model for Cosmological Hyperfluids, that is fluids with intrinsic hypermomentum that induce spacetime torsion and non-metricity. Imposing the Cosmological Princi…
Linear Transformations on Affine-Connections
Damianos Iosifidis
We state and prove a simple Theorem that allows one to generate invariant quantities in Metric-Affine Geometry, under a given transformation of the affine connection. We start by a…
General Teleparallel Quadratic Gravity
Jose Beltrán Jiménez, Lavinia Heisenberg, Damianos Iosifidis +2
In this Letter we consider a general quadratic parity-preserving theory for a general flat connection. Imposing a local symmetry under the general linear group singles out the gene…
Metric-Affine Gravity and Cosmology/Aspects of Torsion and non-Metricity in Gravity Theories
Damianos Iosifidis
This Thesis is devoted to the study of Metric-Affine Theories of Gravity and Applications to Cosmology. The thesis is organized as follows. In the first Chapter we define the vario…
Exactly Solvable Connections in Metric-Affine Gravity
Damianos Iosifidis
This article presents a systematic way to solve for the Affine Connection in Metric-Affine Geometry. We start by adding to the Einstein-Hilbert action, a general action that is lin…
The Raychaudhuri equation in spacetimes with torsion and non-metricity
Damianos Iosifidis, Christos G. Tsagas, Anastasios C. Petkou
We introduce and develop the 1+3 covariant approach to relativity and cosmology to spacetimes of arbitrary dimensions that have nonzero torsion and do not satisfy the metricity con…
