Abstract (en)
A popular class of the inflationary cosmological models is based
on an introduction of a scalar field with nonstandard tachyonic
Lagrangian of the Dirac-Born-Infeld (DBI) type. A potentially
fundamental role of the tachyon fields in the braneworld cosmology
was proposed by A. Sen. Research in this PhD thesis is
motivated by Randall-Sundrum (RSII) cosmological model. The
main objective of the research is to formulate and solve an analytical-
numerical inflationary model with DBI-tachyon field and
RSII model with an additional radion field, as well computation
of observational parameters. Obtained results are in a good
agreement with the real astrophysical data and provide a better
understanding of the role of strings and branes in modern cosmology.
The results indicated that role of radion in an initial
RSII setup is less important than expected.

“Data exchange” service offers individual users metadata transfer in several different formats. Citation formats are offered for transfers in texts as for the transfer into internet pages. Citation formats include permanent links that guarantee access to cited sources. For use are commonly structured metadata schemes : Dublin Core xml and ETUB-MS xml, local adaptation of international ETD-MS scheme intended for use in academic documents.
