The successful extension of the theory beyond this case was a major step.

This extension of the theory enables the evaluation of the Nth higher derivative via an elegant mathematical framework.

In practice, what often happens is that a new theory is devised that is really an extension of the previous theory.

He saw his work as an extension of the theory of evolution by Charles Darwin (1809-1882).

Later in the same 1960 publication Solomonoff describes his extension of the single-shortest-code theory.

Ulm's original proof was based on an extension of the theory of elementary divisors to infinite matrices.

"I think the work is an extension of the theory rather than a direct contradiction."

The classical theory can be seen to challenge standard pictures of causality, thus signaling either a breakdown or a need for extension of the theory.

It began as an extension of the neoclassical theory of economic growth, accounting for non-renewable natural resources as a factor of production.

Of course, these assertions are not widely accepted; they are extensions of the theory, not exceptions to it.
