Abstract: It is first shown in this paper that, whenever it exists, the coincidence degree of the left-hand member of an autonomous differential equation

$\displaystyle x' - {\text{g}}(x) = 0$

, in the space of periodic functions with fixed period $ \omega $, can be computed in terms of the Brouwer degree of $ {\text{g}}$. This result provides efficient continuation theorems specially for $ \omega $-periodic perturbations of autonomous systems. Extensions to differential equations in flow-invariant ENR's are also given.
