Κοσμικό Φως: Αρχέγονο και Ανέσπερο

Το Κέντρο Ερευνών Αστρονομίας και Εφηρμοσμένων Μαθηματικών της Ακαδημίας Αθηνών (ΚΕΑΕΜ) οργάνωσε μια σειρά εκλαϊκευτικών ομιλιών στο πλαίσιο του Διεθνούς Έτους Φωτός 2015.

Το 2015 έχει ανακηρυχθεί από την UNESCO ως «Διεθνές Έτος Φωτός και Τεχνολογιών με βάση το Φως». Στόχος του Διεθνούς Έτους είναι να αναδείξει, σε παγκόσμιο επίπεδο, τον τρόπο με τον οποίο το φως και οι βασισμένες σε αυτό τεχνολογίες επηρεάζουν κάθε πτυχή της ανθρώπινης ζωής. Οι εννέα (9) ομιλίες δόθηκαν από τους ερευνητές και τους συνεργάτες του ΚΕΑΕΜ και αφορούσαν το φως όπως αυτό γίνεται αντιληπτό από τις Θετικές Επιστήμες. Γι αυτόν το λόγο ο κύκλος των ομιλιών είχε τον γενικό τίτλο “Κοσμικό Φως – Αρχέγονο και Ανέσπερο” και είχε ως στόχο να παρουσιάσει τον τρόπο που οι πληροφορίες που μεταφέρει το φως επηρεάζουν την αντίληψη που έχει ο άνθρωπος για το Σύμπαν.

Οι διαλέξεις δόθηκαν σε δύο περιόδους (Μάιο – Ιούνιο και Σεπτέμβριο – Οκτώβριο) στο κεντρικό κτήριο της Ακαδημίας Αθηνών (Ανατολική Αίθουσα) κάθε δεύτερη Τετάρτη στις 7μ.μ.

Finsler Geometry, Lorentz Violation and Cosmology

Panayiotis Stavrinos
Dept. of Mathematics, University of Athens

Abstract:

We present the Lorentz Violation in a Cosmological framework based on General Very Special Relativity (GVSR) and we connect the Finsler Geometry with Friedmann - Robertson - Walker model for the GVSR-cosmology. We also introduce the Extended Finsler - Randers Cosmology (EFR) by using extended curvature theory and we get the modified Friedmann- equations. The resulting model is free of observational inconsistencies. This can mimic the dark energy and modified gravity describing a large class of scale-factor evolutions .We also mention the connection of EFR and Lorentz Violation with dark energy and modified gravity in the cosmological framework.

We finally discuss the field equations and dispersion relation for a weak anisotropic metric tensor in the framework of a Finslerian tangent bundle.
