examples of empty set

As an example, think of the set of piano keys on a guitar. { bidder: 'triplelift', params: { inventoryCode: 'Cambridge_HDX' }}, { bidder: 'criteo', params: { networkId: 7100, publisherSubId: 'cdo_mpuslot' }}, bids: [{ bidder: 'rubicon', params: { accountId: '17282', siteId: '162036', zoneId: '776156', position: 'atf' }}, In any topological space X, the empty set and the whole space X are both clopen.. Now consider the space X which consists of the union of the two open intervals (0,1) and (2,3) of R.The topology on X is inherited as the subspace topology from the ordinary topology on the real line R.In X, the set (0,1) is clopen, as is the set (2,3).This is a quite typical example: … An intersection or a subset of a non-empty set, though, may possibly be empty.
