Abstract
We attempt to provide a mesoscopic treatment of the origin of black hole entropy in [Formula: see text]-dimensional spacetimes. We treat the case of horizons having space-like sections [Formula: see text] which are topological spheres, following Hawking’s and the Topological Censorship theorems. We use the injectivity radius of the induced metric on [Formula: see text] to encode the linear dimensions of the elementary cells giving rise to such entropy. We use the topological entropy of [Formula: see text] as the fundamental quantity expressing the complexity of [Formula: see text] on which its entropy depends. We point out the significance, in this context, of the Berger and Croke isoembolic inequalities.
