Universe: Special Issue “F(R) Gravity”

Dear Colleagues,

F(R) gravity plays a prominent role in the description of gravitational phenomena at large and astrophysical scales. Among the various modified gravity proposals, the F(R) gravity framework is the conceptually simplest generalization of Einstein’s gravity, and has attracted the interest of many cosmologists. In this special issue, the focus will be on applications of F(R) gravity at large and astrophysical scales. We aim to highlight a plethora of theoretical proposals that find explanation in the context of F(R) gravity, both in cosmology and in astrophysics. In view of the current observational data and also due to the upcoming observations, this issue aims to gather all the up to date facts with regard to F(R) gravity applications. All the above problems maybe also be considered in frames of other modified gravities, like modified Gauss-Bonnet gravity, string-inspired theory, teleparallel gravity, Born-Infeld type gravity or non-minimal modified gravity.

Geometric Foundations of Gravity in Tartu, Estonia

Geometric Foundations of Gravity in Tartu

is a conference dedicated to the geometric foundations of gravity theories that will take place August 28 – September 1, 2017 in Tartu, Estonia. The aim of this conference is to gather experts on various alternative and modified approaches to gravity, as well as observations.

The main topics include:

* Gauge theories of gravity (Poincare, teleparallel, …)
* Extended field content and related theories ((multi)scalar-vector-tensor theories, Horndeski, f(R) gravity, generalized Proca, massive gravity and bimetric theories)
* Beyond Lorentzian geometry (Finsler geometry, modified dispersion relations)
* Observational evidence for GR and beyond

The conference is organized by the Laboratory of Theoretical Physics, University of Tartu, Estonia.

Invited speakers are:

-Salvatore Capozziello (Napoli, Italy)
-Friedrich W. Hehl (Cologne, Germany)
-Lavinia Heisenberg (Zurich, Switzerland)
-Tomi S. Koivisto (Stockholm, Sweden)
-Claus Laemmerzahl (Bremen, Germany)
-Yuri N. Obukhov (Moscow, Russia)
-Sergei D. Odintsov (Barcelona, Spain)
-Jose G. Pereira (Sao Paulo, Brazil)
-Frederic Schuller (Erlangen, Germany)

The conference includes a social program including a presentation of the history of gravitational physics in Estonia, a public lecture and an excursion to Estonian natural heritage sites.

Registration is open and possible via the conference homepage
