Scalar-tensor gravity in the Palatini approach

Understand

The main objective of this thesis is to discuss scalar-tensor theories in the Palatini approach.

• Both scalar-tensor theories and Palatini formalism are means of alternating classical theory of gravity, general relativity, in order to account for phenomena being seemingly unexplainable on the ground of the Einstein theory or to serve as toy models used to test limitations of the theory in question.
• In the literature, both Palatini approach and scalar-tensor theories have been widely discussed, but there are very few - if none - authors writing about a merge of these two ideas.
• The present paper is a result of an insufficient attention given to the topic of scalar-tensor theories in Palatini formalism.
