Important concepts in numerical analysis and related areas

What-Is

This is a series of “What Is” articles, which give brief descriptions of important concepts in numerical analysis and related areas, with a focus on topics that arise in my research.

My aim is for the articles to adhere to the following criteria.

  • The posts are no more than two or three screenfuls (about 500 words).
  • The posts contain a minimum of mathematical symbols and equations and a minimum of citations.
  • They are accessible to upper level undergraduate students in any mathematically oriented subject.
  • The list of references given for further reading is very small and concentrates on those that are broad, readable, and contain further references to the literature.

The articles are available in blog form at https://nhigham.com/category/what-is/ and are provided in PDF form in this repository. The PDF files contain hyperlinks, which are clickable in the PDF but not visible in a printout.
