spelling Diffusion method in field theories with fakeonsCalcagni, GianlucaHigh Energy Physics - TheoryGeneral Relativity and Quantum CosmologyphysicsRelativity14 pages, 1 figureWe adapt the diffusion method employed in fundamentally nonlocal field theories to determine the number of initial conditions for the classicized dynamics of unitary field theories with fakeons, characterized by inverse powers of the d'Alembertian operator $\Box$. We show that this number is two and we recover all the results obtained with a direct calculation elsewhere, including explicit solutions of linear toy models. Possible applications to nonlocal gravity are discussed.The author is supported by Grant No. PID2023-149018NB-C41 funded by the Spanish Ministry of Science, Innovation and Universities MCIN/AEI/10.13039/501100011033Peer reviewedAmerican Physical SocietyMinisterio de Ciencia, Innovación y Universidades (España)SCOAP#NODATA#Consejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]202620262026info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Publisher's versioninfo:eu-repo/semantics/publishedVersionhttp://hdl.handle.net/10261/427741http://arxiv.org/abs/2510.15157v2reponame:DIGITAL.CSIC.
