In the paper I am trying to understand it's concept. But with the following sentence makes me confusing.# Messages are the unit of communication1Reference to1All physically computable functions can be implemented using the lambda calculus. It is a consequence of the Actor Model thatthere are some computations that cannot be implemented in the lambda calculus.My question, What are there computations that cannot be implemented in Lambda calculus ?thanks.Minglei.
