This book prepares graduate students for research in numerical analysis/computational mathematics by giving a mathematical framework embedded in functional analysis and focused on numerical analysis. This helps them to move rapidly into a research program.

Covers basic results of functional analysis and also some additional topics which are needed in theoretical numerical analysis Exercises at the end of most sections are included (419) Short discussion of the literature, including recommendations for additional reading is provided at the end of each chapter Includes supplementary material: sn.pub/extras
