S-brane solutions with (anti-)self-dual parallel charge density form on a Ricci-flat submanifold
H. Dehnen, V. D. Ivashchuk, V. N. Melnikov
A D-dimensional cosmological model with several scalar fields and antisymmetric (p+2)-form is considered. For dimensions D = 4m+1 = 5, 9, 13, ... and p = 2m-1 = 1, 3, 5, ... we obt…
Regular black holes and black universes
K. A. Bronnikov, H. Dehnen, V. N. Melnikov
We give a comparative description of different types of regular static, spherically symmetric black holes (BHs) and discuss in more detail their particular type, which we suggest t…
Horizon-less Spherically Symmetric Vacuum-Solutions in a Higgs Scalar-Tensor Theory of Gravity
Nils M. Bezares-Roder, Hemwati Nandan, Heinz Dehnen
The exact static and spherically symmetric solutions of the vacuum field equations for a Higgs Scalar-Tensor theory (HSTT) are derived in Schwarzschild coordinates. It is shown tha…
Electromagnetic Duality, Quaternion and Supersymmetric Gauge Theories of Dyons
H. Dehnen, O. P. S. Negi
Starting with the generalized potentials, currents, field tensors and electromagnetic vector fields of dyons as the complex complex quantities with real and imaginary counter parts…
