		<item><title>Multivariable Differential Calculus</title><link>https://www.bubok.es/libros/232902/multivariable-differential-calculus</link><description>Multivariable Differential Calculus is an undergraduate-graduate e-book   on differential calculus of several variables (advanced calculus), which   is written in English language, downloadable through this on-line   bookshop. This book carries out a journey through the fundamentals of   calculus of several variables, following a rigurous methodology which   proves almost all of theoretical results which are treated in the book.   It begins stating the basic notions on topology which are used in the   book, and generalizes results when it is possible, it continues with   continuity and differentiable functions, and finally carries out an   introduction to differential equations and differentiable manifolds.</description></item></channel></rss>
