Summary
| Description |
English: Representation by definition of the open Neighbourhood sets of the points in the Moore Plane also known as Nemytskii's tangent disk topology. , is a topological space. It is a completely regular Hausdorff space (also called Tychonoff space) that is not normal. It is named after Robert Lee Moore and Viktor Vladimirovich Nemytskii.
Italiano: Rappresentazione del Piano di Moore a partire dagli intorni aperti dei punti giacenti sul semipiano. l piano di Moore (Moore plane in inglese), anche detto piano di Niemytzki (o piano di Nemytskii, topologia di Nemytskii dei dischi tangenti), è uno spazio topologico. Questo spazio è completamente regolare T3.5 cioè uno spazio di Tychonoff che però non è uno spazio normale T4. Per questo motivo è spesso utilizzato come esempio della affermazione "T3.5 non implica T4". Il piano di Moore deve il suo nome al matematico statunitense Robert Lee Moore e nella sua dicitura alternativa a Viktor Vladimirovich Nemytskii. |
