### Notation for Scholarly Works Involving Interval Computations

R. Baker Kearfott

There have been several notations in common use in the literature on interval
computations. However, consistency has been lacking in separate papers
written by different researchers. There has been a suggestion that the
notation described in my recent book, *Rigorous
Global Search: Continuous Problems* be used as a standard. Click
on one of the following for details of this notation.

Although this notation is not official, and has not been fully discussed
among researchers in interval computations, I am making generic versions
of the LaTeX files from my book available upon request. A small file that
has the essentials described in the DVI and Postscript explanations above
is ivl_ess.sty.

To get the complete set of definitions in the book *Rigorous Global
Search*, you need the following set of files:

- reptdefs.tex
- report-specials.tex
- general-defs.tex

Each of these files is needed for the entire set of definitions. To
use, put the line \input reptdefs.tex in the LaTeX file. One suggested
modification is to use lower case boldface, rather than upper case boldface
for interval vectors, and to reserve uppercase for matrices and higher-order
tensors.
