About: Densely defined operator

An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

In mathematics – specifically, in operator theory – a densely defined operator or partially defined operator is a type of partially defined function. In a topological sense, it is a linear operator that is defined "almost everywhere". Densely defined operators often arise in functional analysis as operations that one would like to apply to a larger class of objects than those for which they a priori "make sense".

  • 数学の、特に作用素論の分野における稠密に定義された作用素（ちゅうみつにていぎされたさようそ、英語: densely defined operator）とは、部分的に定義されたある種の関数のことで、位相的な意味では「ほとんど至る所」定義された線形作用素のことである。稠密に定義された作用素は、関数解析学の分野において、先天的に「意味を持つ」ような対象よりもより広いクラスへと応用されるような作用素として登場する。 (ja)
