2 unusual facts about Functional analysis


Food coating

Information need to be gathered carefully along the above mentioned lines : base product, end product, ingredient, production constraints… Functions to fulfilly need to be clearly identified through Functional analysis, value analysis.

Order theory

A simple example of an order theoretic property for functions comes from analysis where monotone functions are frequently found.


Behavioral activation

for depression is Charles Ferster's functional analysis of depression.

Beppo-Levi space

In functional analysis, a branch of mathematics, a Beppo-Levi space, named after Beppo Levi, is a certain space of generalized functions.

Dunford–Pettis property

In functional analysis, the Dunford–Pettis property, named after Nelson Dunford and B. J. Pettis, is a property of a Banach space stating that all weakly compact operators from this space into another Banach space are completely continuous.

Dunford–Schwartz theorem

In mathematics, particularly functional analysis, the Dunford–Schwartz theorem, named after Nelson Dunford and Jacob T. Schwartz states that the averages of powers of certain norm-bounded operators on converge in a suitable sense.

J. N. Reddy

He has made significant seminal contributions in the specific areas of finite element method, plate theory, solid mechanics, variational methods, mechanics of composites, functionally graded materials, fracture mechanics, plasticity, biomechanics, classical and non-Newtonian fluid mechanics, and applied functional analysis.

Semifield

In ring theory, combinatorics, functional analysis, and theoretical computer science, a semifield is a semiring (MSC 16Y60) (S,+,·) in which all elements have a multiplicative inverse.

Volterra operator

In mathematics, in the area of functional analysis and operator theory, the Volterra operator, named after Vito Volterra, represents the operation of indefinite integration, viewed as a bounded linear operator on the space L2(0,1) of complex-valued square integrable functions on the interval (0,1).

Zorn's lemma

It occurs in the proofs of several theorems of crucial importance, for instance the Hahn–Banach theorem in functional analysis, the theorem that every vector space has a basis, Tychonoff's theorem in topology stating that every product of compact spaces is compact, and the theorems in abstract algebra that every nonzero ring has a maximal ideal and that every field has an algebraic closure.

Baire category theorem

Note that neither of these statements implies the other, since there are complete metric spaces which are not locally compact (the irrational numbers with the metric defined below; also, any Banach space of infinite dimension), and there are locally compact Hausdorff spaces which are not metrizable (for instance, any uncountable product of non-trivial compact Hausdorff spaces is such; also, several function spaces used in Functional Analysis; the uncountable Fort space).

Behavioral activation

Behavioral activation owes its basis to Charles Ferster's Functional Analysis of Depression (1973) which developed B.F. Skinner's idea of depression, within his analysis of motivation, as a lack of reinforcement.

Gateway Cassette

The Gateway Technology provides a quick and highly efficient way to move genes into a multiple vector system for functional analysis and protein expression (Invitrogen, Gateway Technology Manual, 2003).

POSDCORB

Gulick states that his statement of the work of a chief executive is adapted from the functional analysis elaborated by Henri Fayol in his "Industrial and General Administration".
