General solutions for flat Friedmann universe filled by perfect fluid and scalar field with exponential potential
H. Dehnen, V. R. Gavrilov, V. N. Melnikov
We study integrability by quadrature of a spatially flat Friedmann model containing both a minimally coupled scalar field with an exponential potential $V(ϕ)\sim\exp[-\sqrt{6}σ…
On black hole solutions in model with anisotropic fluid
H. Dehnen, V. D. Ivashchuk, V. N. Melnikov
A family of spherically symmetric solutions in the model with 1-component anisotropic fluid is considered. The metric of the solution depends on a parameter q > 0 relating radial p…
Regularization of Non-Linear Spinor Field Models by Discrete Symmetries
Bertfried Fauser, Heinz Dehnen
We generalize a regularization method of Stumpf 1984 in the case of non-linear spinor field models to fourth order theories and to non-scalar interactions. The involved discrete sy…
Isospin from Spin by Compositenes
Bertfried Fauser, Heinz Dehnen
We propose a new method to generate the internal isospin degree of freedom by non-local bound states. This can be seen as motivated by Bargmann-Wigner like considerations, which or…
Integration of Einstein's Equations in the Weak Field Domain Using the "Einstein" Gauge
E. Hitzer, H. Dehnen
We propose a new alternative gauge for the Einstein equations instead of the de Donder gauge, which allows in the limit of weak fields a straightforward integration of these equati…
