Projects

• Fan Calculus
  An attempt to develop a new calculus (on the order of the predicate calculus, algebra, the differential calculus (“the calculus”), the λ-calculus, etc.) for reasoning about objects — where the issue of identity of objects is taken to derive from what is predicated of them, rather than being an intrinsic feature. Therefore no built-in notion of identity of anything, general or particular — including the elements of the calculus itself.
