For those needing university-level syllabus context or specific lecture notes based on this text, institutions like IET DAVV recommend this book for Numerical Analysis and Integral Equation courses.
: A detailed summary of integral equations based on Swarup's book is available on Research Papers
If you are on a tight budget, there are excellent free resources available legally online that can supplement your learning:
Integral Equations by Shanti Swarup is a protected copyrighted work and not legally available for free download as a complete PDF, you can access substantial study materials and purchase the official text through the following resources: Official Online & Purchase Options
In Volterra equations, at least one of the limits of integration is a variable (usually the upper limit). The text details:
: Where the limits of integration are fixed.
Additionally, maybe there are free textbooks or lecture notes on integral equations available online. I can mention resources like MIT OpenCourseWare, arXiv, or other open educational resources. Also, recommend checking online libraries like Open Library or Project Gutenberg, though these are more for public domain texts. If the book is old enough, maybe it's in the public domain in India, but I need to be careful not to assume that without confirmation.
