Transform methods provide a bridge between the commonly used method of separation variables and numerical techniques for solving linear partial differential equations

Transform methods provide a bridge between the commonly used method of separation variables and numerical techniques for solving linear partial differential equations. While in some ways similar to separation of variables and numerical transform methods can be effective for a wider class of problems. Even when the inverse of the transform cannot be found analytically, numeric and asymptotic techniques now exist for their inversion. Because the problem retains some of its analytic aspects, one can gain greater physical insight than typically obtained from a purely numerical approach.

A textbook or reference for applied physicists or mathematicians; geophysicists; or civil, mechanical, or electrical engineers. It assumes the usual undergraduate sequence of mathematics in engineering or the sciences, the traditional calculus, differential equations, and Fourier and Laplace transforms. It explains how to use those and the Hankel transforms to solve linear partial differential equations that are encountered in engineering and sciences.

This essential text/reference draws from the latest literature on transform methods to provide in-depth discussions on the joint transform problem, the Cagniard-de Hoop method, and the Wiener-Hopf technique. Some 1,500 references are included as well. Format Hardback 512 pages. Dimensions 156 x 235 x 3. 5mm 907g. Publication date 16 Feb 1994. Publisher Taylor & Francis Inc.

Many differential equations cannot be solved using symbolic computation ("analysis"). In addition, some methods in numerical partial differential equations convert the partial differential equation into an ordinary differential equation, which must then be solved. For practical purposes, however – such as in engineering – a numeric approximation to the solution is often sufficient. The algorithms studied here can be used to compute such an approximation. An alternative method is to use techniques from calculus to obtain a series expansion of the solution.

Transform methods for solving partial differential equations. In the present paper, a new method of solving Bessel's differential equation is given using the L2-transform.

Symbolic & Numeric Computation. Transform Methods for Solving Partial Differential Equations. This new book deals with the construction of finite-difference (FD) algorithms for three main types of equations: elliptic equations, heat equations, and gas dynamic equations in Lagrangian form. These methods can be applied to domains of arbitrary shapes. The construction of FD algorithms for all.

**Transform Methods for Solving Partial Differential Equations, Second Edition** illustrates the use of Laplace, Fourier, and Hankel transforms to solve partial differential equations encountered in science and engineering. The author has expanded the second edition to provide a broader perspective on the applicability and use of transform methods and incorporated a number of significant refinements:

New in the Second Edition:

· Expanded scope that includes numerical methods and asymptotic techniques for inverting particularly complicated transforms

· Discussions throughout the book that compare and contrast transform methods with separation of variables, asymptotic methods, and numerical techniques

· Many added examples and exercises taken from a wide variety of scientific and engineering sources

· Nearly 300 illustrations--many added to the problem sections to help readers visualize the physical problems

· A revised format that makes the book easier to use as a reference: problems are classified according to type of region, type of coordinate system, and type of partial differential equation

· Updated references, now arranged by subject instead of listed all together

As reflected by the book's organization, content, and many examples, the author's focus remains firmly on applications. While the subject matter is classical, this book gives it a fresh, modern treatment that is exceptionally practical, eminently readable, and especially valuable to anyone solving problems in engineering and the applied sciences.
