Complemented subspace: Applications, Motivation & Definition

In the branch of mathematics called functional analysis, a complemented subspace of a topological vector space X , {\displaystyle X,} is a vector subspace M {\displaystyle M} for which there exists some other vector subspace N {\displaystyle N} of X , {\displaystyle X,} called its (topological) complement in X {\displaystyle X} , such that X…
