Here, We provided to Functional Analysis Hand Written Note By P Kalika. Functional analysis is a branch of mathematical analysis, the core of which is formed by the study of vector spaces endowed with some kind of limit-related structure (e.g. inner product, norm, topology, etc.) and the linear functions defined on these spaces and respecting these structures in a suitable sense.

The historical roots of functional analysis lie in the study of spaces of functions and the formulation of properties of transformations of functions such as the Fourier transform as transformations defining continuous, unitary, etc. operators between function spaces. This point of view turned out to be particularly useful for the study of differential and integral equations.

The usage of the word functional as a noun goes back to the calculus of variations, implying a function whose argument is a function. The term was first used in Hadamard’s 1910 book on that subject. However, the general concept of a functional had previously been introduced in 1887 by the Italian mathematician and physicist Vito Volterra.

The theory of nonlinear functionals was continued by students of Hadamard, in particular Fréchet and Lévy. Hadamard also founded the modern school of linear functional analysis further developed by Riesz and the group of Polish mathematicians around Stefan Banach.

In modern introductory texts to functional analysis, the subject is seen as the study of vector spaces endowed with a topology, in particular infinite-dimensional spaces. In contrast, linear algebra deals mostly with finite-dimensional spaces and does not use topology. An important part of functional analysis is the extension of the theory of measure, integration, and probability to infinite-dimensional spaces, also known as infinite-dimensional analysis.

Functional analysis, Branch of mathematical analysis dealing with functionals, or functions of functions. It emerged as a distinct field in the 20th century, when it was realized that diverse mathematical processes, from arithmetic to calculus procedures, exhibit very similar properties. A functional, like a function, is a relationship between objects, but the objects may be numbers, vectors, or functions. Groupings of such objects are called spaces.

Differentiation is an example of a function because it defines a relationship between a function and another function (it’s derivative). Integration is also functional. Functional analysis focuses on classes of functions, such as those that can be differentiated or integrated.

Functional analysis is a department of mathematical evaluation, the core of which is formed via the examination of vector spaces endowed with some kind of restrict-related structure and the linear functions described in those spaces and respecting these structures in a suitable sense.

This point of view grew to become out to be particularly useful for the examination of differential and crucial equations. Free download PDF Functional Analysis Hand Written Note By P Kalika.

**CSIR NET Exam Pattern 2020**

NTA has released the CSIR NET Exam Pattern for all the five subjects. Candidates will have to pick any one subject and apply for the same. The CSIR UGC NET exam pattern and marking scheme are different for all the subjects. However, Part A syllabus is the same for all subjects.

- CSIR NET question paper for each subject is divided into three parts namely, Part A, Part B, Part C.
- All three sections are compulsory.
- There will be no break between the three sections.
- All 3 parts will have only Multiple Choice Questions (MCQs).
- The CSIR NET 2020 will be conducted for a total of 200 marks.
- The exam will be held for a duration of 3 hours.
