Metric-affine gravity effects on terrestrial (exo-)planets profiles
Aleksander Kozak, Aneta Wojnar
Mass-radius relations of homogeneous cold spheres are obtained for six solid materials commonly found in terrestrial planets. An additional degeneracy in the (exo-)planets' profile…
Invariant quantities of Scalar-Tensor Theories for stellar structure
Aleksander Kozak, Aneta Wojnar
We present the relativistic hydrostatic equilibrium equations for a wide class of gravitational theories possessing a scalar-tensor representation. It turns out that the stellar st…
Equivalence of inflationary models between the metric and Palatini formulation of scalar-tensor theories
Laur Järv, Alexandros Karam, Aleksander Kozak +3
With a scalar field non-minimally coupled to curvature, the underlying geometry and variational principle of gravity - metric or Palatini - becomes important and makes a difference…
New class of hybrid metric-Palatini scalar-tensor theories of gravity
Andrzej Borowiec, Aleksander Kozak
A class of scalar-tensor theories (STT) including a non-metricity that unifies metric, Palatini and hybrid metric-Palatini gravitational actions with non-minimal interaction is pro…
Learning ReLU Networks on Linearly Separable Data: Algorithm, Optimality, and Generalization
Gang Wang, Georgios B. Giannakis, Jie Chen
Neural networks with REctified Linear Unit (ReLU) activation functions (a.k.a. ReLU networks) have achieved great empirical success in various domains. Nonetheless, existing result…
Scalar-tensor gravity in the Palatini approach
Aleksander Kozak
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 classic…
