sumspace
sumspace is a term that can refer to several related mathematical concepts, primarily within the fields of linear algebra and functional analysis. At its core, it denotes a space formed by combining or summing other spaces.
In linear algebra, sumspace often refers to the direct sum of vector spaces. If V and W
More broadly, in functional analysis, sumspace can refer to the sum of subspaces within a larger vector
The term can also appear in more abstract settings, such as in the context of Banach spaces
