T-Duality Effects in Electrodynamics: The (2+1)-dimensional Case
Patricio Gaete, Piero Nicolini
We investigate the interplay between T-duality and (2+1)- dimensional electrodynamics, revealing a relationship between short and large length scales of the gauge potential. Our fi…

Geodesic completeness from string T-duality
Kimet Jusufi, Piero Nicolini
By studying the Raychaudhuri equation for the gravitational force resulting from a string T-duality modified propagator, we present an analysis of the geodesic compression beyond t…
