MathWorld Terms and Conditions of Use
Access to MathWorld is granted on the following terms:
Readers are encouraged to use the contents of these pages for education and enjoyment, but these pages may
not be copied, mirrored, redistributed, printed, or
reproduced in bulk without permission. Reproduction for commercial purposes is not
permitted, nor is use of robots to create archival copies.
Limited use of
material for academic research and teaching is permitted, providing conventional
citation standards are followed. Access to the MathWorld website will be blocked
to subnets violating these terms. Indiscriminant use of prefetching results in bandwidth degredation
for other MathWorld users and may violate the above proscription against bulk downloading.
Since excessive use of prefetching has resulted in extensive imposition of blocking, MathWorld
now denies access to prefetching software and browsers. To re-enable access, you can simply turn off prefetching
in your browser.
Contributions are welcome. All contributions will be reviewed for
correctness and suitability, and may be edited for content and/or presentation. Material should be specific,
concise, verifiable, and preferably useful and interesting. Every attempt will be made to recognize contributors
for their assistance and to identify contributed entries on the MathWorld website.
When making a submission, unless you request otherwise, you are granting non-exclusive permission to include
contributed material (or edited versions thereof) in MathWorld, as well as in any derivative works in any
medium, including but not limited to book form or CD-ROM as further indicated in the
permission form. Please see the FAQ on
contributing for additional details about the formatting and submission of contributed material.
