Techniques of Functional Analysis for Differential and Integral Equations describes a variety of powerful and modern tools from mathematical analysis, for graduate study and further research in ordinary differential equations, integral equations and partial differential equations. Knowledge of these techniques is particularly useful as preparation for graduate courses and PhD research in differential equations and numerical analysis, and more specialized topics such as fluid dynamics and control theory. Striking a balance between mathematical depth and accessibility, proofs involving more technical aspects of measure and integration theory are avoided, but clear statements and precise alternative references are given . The work provides many examples and exercises drawn from the literature.

Key Features

  • Provides an introduction to mathematical techniques widely used in applied mathematics and needed for advanced research in ordinary and partial differential equations, integral equations, numerical analysis, fluid dynamics and other areas
  • Establishes the advanced background needed for sophisticated literature review and research in differential equations and integral equations
  • Suitable for use as a textbook for a two semester graduate level course for M.S. and Ph.D. students in Mathematics and Applied Mathematics


Graduate students and 1st year PhDs across applied mathematics, mathematics and in disciplines making use of applied mathematics

"For readers with interest in the theory or application of differential equations, integral equations, optimization, or numerical analysis, Techniques of Functional Analysis for Differential and Integral Equations is a very valuable resource. I highly recommend this book to any such person. I also believe that the book can serve as a nice supplement to more abstract texts on functional analysis, helping one to see how the abstract theory influences thinking about other areas of mathematics."--MAA Reviews
