Possible wormholes in a brane world
K. A. Bronnikov, Sung-Won Kim
The condition R=0, where R is the four-dimensional scalar curvature, is used for obtaining a large class (with an arbitrary function of r) of static, spherically symmetric Lorentzi…
Global Monopole in General Relativity
Kirill A. Bronnikov, Boris E. Meierovich, Evgeny R. Podolyak
We consider the gravitational properties of a global monopole on the basis of the simplest Higgs scalar triplet model in general relativity. We begin with establishing some common…
Scalar fields in multidimensional gravity. No-hair and other no-go theorems
K. A. Bronnikov, S. B. Fadeev, A. V. Michtchenko
Global properties of static, spherically symmetric configurations of scalar fields of sigma-model type with arbitrary potentials are studied in dimensions, including space-time…
Possible time variations of G in scalar-tensor theories of gravity
K. A. Bronnikov, V. N. Melnikov, Mario Novello
We estimate the possible variations of the gravitational constant G in the framework of a generalized (Bergmann-Wagoner-Nordtvedt) scalar-tensor theory of gravity on the basis of t…
Nonsingular multidimensional cosmologies without fine tuning
K. A. Bronnikov, J. C. Fabris
Exact cosmological solutions for effective actions in D dimensions inspired by the tree-level superstring action are studied. For a certain range of free parameters existing in the…
Charged wormholes with non-minimally coupled scalar fields. Existence and stability
K. A. Bronnikov, S. Grinyok
Static, spherically symmetric, traversable wormhole solutions with electric or magnetic charges are shown to exist in general relativity in the presence of scalar fields nonminimal…
