  • computability theory — (mathematics)   The area of theoretical computer science concerning what problems can be solved by any computer. A function is computable if an algorithm can be implemented which will give the correct output for any valid input.

The most well-known is the halting problem, the busy beaver problem is less famous but just as fascinating.
