WebDisk (mathematics) In geometry, a disk (also spelled disc) [1] is the region in a plane bounded by a circle. A disk is said to be closed if it contains the circle that constitutes its boundary, and open if it does not. [2] For a radius, , an open disk is usually denoted as and a closed disk is . However in the field of topology the closed disk ... WebOpen sets are the fundamental building blocks of topology. In the familiar setting of a metric space, the open sets have a natural description, which can be thought of as a generalization of an open interval on the real number line. Intuitively, an open set is a set that does not contain its boundary, in the same way that the endpoints of an interval are …
