domain over
A pair , where is an arcwise-connected Hausdorff space and is a local homeomorphism, called a projection. Covering domains are encountered in the analytic continuation of holomorphic functions. For every analytic (possibly multivalent) function in a domain there is a corresponding covering domain with a projection , just as for every analytic function of one complex variable there is a corresponding Riemann surface; the function is single-valued on . Covering domains are also called Riemann domains.
