Webof the complex plane are neither closed nor open. By a neighbourhood of a point z0 in the complex plane, we will mean any open set containing z0. For example, any open "-disk around z0 is a neighbourhood of z0. Let us see that the open and closed "-disks are indeed open and closed, respectively. Let z 2 D"(z0).

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 ... WebWe first define an open ball in a metric space, which is analogous to a bounded open interval in R. De nition 7.18. Let (X,d) be a metric space. The open ball of radius r > 0 and center x ∈ X is the set Br(x) = {y ∈ X: d(x,y) < r}. Example 7.19. Consider R with its standard absolute-value metric, defined in Example 7.3. Then the open ball

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.
