Rodrigo" ], "categories": [ "math.AP" ], "abstract": "The time-fractional diffusion equation is considered, where the time derivative is either of Caputo or Riemann-Liouville type. The solution of a general initial-boundary value problem with time-dependent boundary conditions over bounded and unbounded domains is derived using the embedding method. The solution of the initial-boundary value problem, expressed in terms of a two-parameter auxiliary function, is used to obtain analytical solutions of moving boundary problems. In particular, a 'fractional' analogue of the Neumann solution to a classical Stefan problem for melting ice is found.", "revisions": [ { "version": "v1", "updated": "2022-12-06T07:45:17.000Z" } ], "analyses": { "subjects": [ "26A33", "35R11", "35K05" ], "keywords": [ "time-fractional diffusion equation", "moving boundary problems", "analytical solutions", "general initial-boundary value problem", "two-parameter auxiliary function" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
