  • Alberto Garoffolo,
  • Lyudmila Kovalchuk,
  • Hanna Nelasa and
  • Roman Oliynykov

24 November 2021

The paper is devoted to the investigation of the distributed proof generation process, which makes use of recursive zk-SNARKs. Such distributed proof generation, where recursive zk-SNARK-proofs are organized in perfect Mercle trees, was for the first...

  • Alessio Orlandi

15 October 2015

We review some features of Bose–Einstein condensate (BEC) models of black holes obtained by means of the horizon wave function formalism. We consider the Klein–Gordon equation for a toy graviton field coupled to a static matter current in a spherical...
