Geometric Foundations of Gravity 2025

30 Jun 2025, 09:00 → 4 Jul 2025, 16:00 Europe/Tallinn

Physicum (University of Tartu)

Christian Pfeifer (University of Bremen, ZARM), Laur Järv (University of Tartu), Margus Saal, Sotirios Karamitsos (University of Tartu)

The conference is dedicated to the various approaches to gravity that venture beyond the basic formalism of general relativity, i.e., the description in terms of a massless metric field in Riemannian geometry derived from the Einstein-Hilbert action. The topics will range from the foundational issues to the applications in cosmology, gravitational waves, black holes, and other objects.

The topics under discussion include for instance:

• Extensions of general relativity (metric-affine gravity, Poincare gauge gravity, scalar/vector/tensor gravity, teleparallel gravity, massive gravity, bi-metric gravity, etc);
• Phenomenology of extended gravity (black holes, ordinary/neutron/boson/grava stars, gravitational waves, cosmology, dark energy, dark matter, galaxies, early universe etc);
• Beyond Lorentzian geometry in classical and quantum gravity (doubly/deformed relativity, standard model extension, Hamilton geometry, Finsler geometry, etc).

Workshop on computer algebra in gravity

The last day of the conference is planned for hands on tutorial workshops on using computer algebra in gravity theory calculations, focussing on free specialized software packages Cadabra and SymPy (tensor).

The plenary speakers include:

• Salvatore Capozziello (Napoli)
• Dražen Glavan (Prague)
• Kirill Krasnov (Nottingham)
• Antonino Marciano (Shanghai, Frascati)
• Nicoleta Voicu (Brasov)
• Thomas Złośnik (Gdansk)
