Key Features

Interested in applications, particularly, physicists, technocrats, logicians, computer scientists, applied analystc etc.


Readership

The confluence of two different disciplines, 'Theory des distributions' and the Lambda Calculus.'

Introduce the basic techniques and result in both the field.
An account of classification of distributions as Schwartz distributions and the rest as the Classical distributions (generalized functions).


Description

The first applicability of "Theories des distribution" is what we name as Soboleff-Schwartz approach in differential and partial differential equations. The second applicability may be named as "the removal of the deficiencies of functions "observed in physics, technology etc. The present text carries the aspect of this later type of applications to describe a comprehensive account of new results concerning the value and limit as an operation on Schwartz distribution in one and several variables. This operation has been discussed only in new books i.e. Misra and Lavoine [1986], where a brief account of this operation has been discussed in only few books i.e. Misra and Lavoine [1986], where a brief account of this operation has been shown valid only in one variable cases. Herein, this operation permits a great flexibility in applications, particularly, it provide: as independent theory of lambda calculus (computer science) carries an account about the value of operator, operator problems posed by Logicians; and a brief account of the solution of problems posed in applied physics by physicists concerning the errors in experimental data. Moreover, text presents for the first time an account of classifications of distributions as Schwartz distributions and the rest as classical distributions (generalized functions) which is the objective of Oberwolfach meeting on Generalized functions held in 1989 from the point of views of applications, particularly, among those who are physicists, technocrats, logicians etc. Accordingly, it is excepted that the book will be useful for those who are interested in applications, particularly, physicists, technocrates, logicians, computer scientists, applied analysts etc.
