Abstract
Given a scheme over and a hyperfield which is equipped with topology, we endow the set of -rational points with a natural topology. We then prove that; (1) when is the Krasner hyperfield, is homeomorphic to the underlying space of , (2) when is the tropical hyperfield and is of finite type over a complete non-Archimedean valued field , is homeomorphic to the underlying space of the Berkovich analytificaiton of , and (3) when is the hyperfield of signs, is homeomorphic to the underlying space of the real scheme associated with .
