What does the mathematical theory of Actors have to say about this?

This kind of situation happens quite often with mathematical theories named after real life problems.

So far there is no real evidence of their existence, just some interesting mathematical theories.

I'm not going into the mathematical theory even now.

His paper contained the skeleton even of the mathematical theory.

This work was research toward a practical end that ran from mathematical theory to the operating field.

However, this mathematical theory does not provide a practical way of doing inference.

The problem is to make progress toward a mathematical theory that will give insight into these equations.

His early work was central to founding the mathematical theory of plasticity.

Like mathematical theories and the very process of thought, software cannot be patented.
