Bulk-boundary decompositions and exact perfect fluid stellar distributions
Sudan Hansraj, Christian G. Boehmer, Ndumiso Buthelezi
The decomposition of the Ricci scalar in terms of bulk and boundary terms gives rise to an interesting gravitational field theory as proposed by Böhmer and Jensko (BJ). BJ went on…
Modified gravity: a unified approach
Christian G. Boehmer, Erik Jensko
Starting from the original Einstein action, sometimes called the Gamma squared action, we propose a new setup to formulate modified theories of gravity. This can yield a theory wit…
D=11 cosmologies with teleparallel structure
Christian G. Bohmer, Franco Fiorini, P. A. González +1
The presence of additional compact dimensions in cosmological models is studied in the context of modified teleparallel theories of gravity. We focus the analysis on eleven dimensi…
The regular black hole in four dimensional Born-Infeld gravity
Christian G. Boehmer, Franco Fiorini
In the context of Born-Infeld gravity theories we report the existence of a regular black hole interior representing a spherically symmetric vacuum solution of the theory. It reduc…
Generalised matter couplings in general relativity
Christian G. Boehmer, Sante Carloni
A new class of modified theory of gravity is introduced where the volume form becomes dynamical. This approach is motivated by unimodular gravity and can also be related to Brans-D…
Soliton solutions in geometrically nonlinear Cosserat micropolar elasticity with large deformations
Christian G. Boehmer, Yongjo Lee, Patrizio Neff
We study the fully nonlinear dynamical Cosserat micropolar elasticity problem in space with three dimensionals with various energy functionals dependent on the microrotation $\over…
Geometrically nonlinear Cosserat elasticity in the plane: applications to chirality
Sebastian Bahamonde, Christian G. Boehmer, Patrizio Neff
Modelling two-dimensional chiral materials is a challenging problem in continuum mechanics because three-dimensional theories reduced to isotropic two-dimensional problems become n…
