dc.description.abstract The Eddington-inspired Born-Infeld (EiBI) gravity is a modification of the theory of general relativity inspired by the nonlinear Born-Infeld electrodynamics. The theory is described by a series of higher-curvature terms added to the Einstein-Hilbert action with the parameter κ. The EiBI gravity has several interesting exact neutral and charged black hole solutions. We study the problem of overcharging extremal black hole solutions of EiBI gravity using a charged test particle to create naked singularity. We show that, unlike general relativity, the overcharging could be possible for a charged extremal black hole in EiBI gravity as long as the matter sector is described by usual Maxwell’s electrodynamics. Once the matter sector is also modified in accordance to the Born-Infeld prescription with the parameter b, the overcharging is not possible as long as the parameters obey the condition 4 b2≤1. en_US
