The Origins of Operational Calculus

Operational Calculus, also known as operational analysis, arose from the need to solve differential equations with arbitrary forcing functions. It was developed by physicists and engineers in the early 20th century to address problems in electrical engineering and mechanical systems. Inspired by Laplace transforms, which proved to be useful in solving differential equations, Operational Calculus emerged as a systematic method for solving a wide range of mathematical problems.

Understanding Generalized Functions

Generalized Functions, also known as distributions, are mathematical objects that extend the concept of a traditional function. While traditional functions typically have well-defined values at each point, generalized functions allow the concept of value to be extended to more abstract settings. They are particularly useful in dealing with discontinuities and singularities in mathematical analysis and physics. Generalized functions have found applications in various areas, including signal processing, quantum mechanics, partial differential equations, and more.

Applications and Significance

Operational Calculus and Generalized Functions have undoubtedly left a profound impact on mathematics and several scientific disciplines. Here are some areas where they shine:

Engineering and Physics

In electrical engineering, Operational Calculus helps analyze time-dependent systems and circuits, making it invaluable in areas such as control theory, communication systems, and signal processing. Generalized Functions find extensive use in solving differential equations that model physical phenomena, such as heat conduction, wave propagation, and quantum mechanics.

Image and Signal Processing

Operational Calculus provides powerful tools for representing and manipulating signals and images, essential in applications like image restoration, noise reduction, and image analysis. Generalized Functions play a vital role in signal processing by allowing the use of impulses, Dirac delta functions, and other distributions for modeling signals and systems.

Partial Differential Equations

Operational Calculus enables the efficient solution of partial differential equations by transforming them into algebraic equations. Generalized Functions play a fundamental role in the theory of partial differential equations, helping tackle challenging problems with complex boundary conditions or singularities.

The Development of Operational Calculus

Operational Calculus has evolved over the years, with numerous mathematicians contributing to its development. Notable pioneers include Heaviside, Bromwich, Laplace, and Gelfand. Each mathematician added unique insights and tools to the theory, refining it and expanding its applications.

This brief monograph by a distinguished professor is based on a mathematics course offered at the California Institute of Technology. The majority of students taking this course were advanced undergraduates and graduate students of engineering. A solid background in advanced calculus is a prerequisite.
Topics include elementary and convergence theories of convolution quotients, differential equations involving operator functions, and exponential functions of operators. Tools developed in the preceding chapters are then applied to problems in partial differential equations. Solutions to selected problems appear at the end of the book.
