Quotations of the Month

The Liberty Bell
(from Leviticus 25:10)

Benjamin Franklin, 1755

'Tis better to have loved and flossed
Than never to have flossed at all.

-- after S.J. Bruskin, July 2014

Past quotations of the month.

My Publications and So Forth
A list of published and selected unpublished works.
A list arranged by topics.

My Research Interests
Combinatorics, especially matroids, arrangements of hyperplanes, and the topic to which I devote most of my attention, signed graphs and their relatives: see
The Home Page of Signed, Gain, and Biased Graphs
at which you will find the Mathematical Bibliography, the Glossary, and a glacially growing list of research problems.
And see the New York Times.

Fraktur (German) letters, printed and handwritten forms, from Sheila MacIntyre and Edith Witte, German-English Mathematical Vocabulary, Oliver and Boyd, Edinburgh and London, 1956; second ed. 1966. Higher resolution (2 MB).
