functional analysis
Leonid V. Kantorovich, Victor M. Polterovich · The New Palgrave Dictionary of Economics · 2011
Functional analysis is a branch of mathematics mainly concerned with infinite-dimensional vector spaces and their maps. Elements (points) of certain important specific spaces are functions, hence the term ‘functional analysis’. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
