Differential Equations - Linear Theory and Applications

Differential Equations - Linear Theory and Applications (DELTA) is an e-book based on my teaching of Math2930 Differential Equations and Math2940 Linear Algebra at Cornell. It is in two Parts - the first Part is on Ordinary Differential Equations and the second Part is on Partial Differential Equations. This second Part, I believe, represents an approach different from the standard texts and is a useful resource for students of physics and engineering.

From the back of the book : Differential Equations Linear Theory and Applications (DELTA) is a text cum problem collection on ordinary and partial differential equations. For each topic, a succinct exposition of the theory is followed by a series of problems, ranging from simple to difficult, and dealing with real-world phenomena taken from classical mechanics and vibrations, elasticity theory, electromagnetism and electrical engineering, quantum mechanics, and acoustics.

Some of the problems are my own research work. For example, Tutorial 125 has been published in AIP Chaos, while Tutorial 68 has been published in European Journal of Physics.

DELTA now has bookmarks !! Please use the bookmarks for navigation. The e-file is optimized for two-page viewing - a left hand page of the print version appears as left hand page here and the same holds true for the right hand pages. The file size is 15.3 short megabytes or 14.5 long megabytes.

I wholeheartedly welcome your comments, criticisms, suggestions for improvement and any other feedback. I will be updating the version periodically, correcting errors as they are found.

DELTA is perfectly free to download, distribute and read. However, if you use any result contained here in your paper, book or other academic publication, please cite DELTA. The citation reads as :
