- Editorial work
- I'm on the editorial board of two mathematician-owned journals,
both dedicated to Diamond Open Access, that is, no charges for authors or readers:
These journals are supported by
The Combinatorics Consortium
- I'm also an editor for
- Research software
C code written by UROP student Michael Barany,
to compute the Tutte polynomial of a matrix
over the integers or finite fields of prime order.
some JAVA applets related to phase diagrams
and geochemistry, produced by Sam Peterson.
- Research diagrams!
Lucky am I to have friends who can get computers to draw ...
- the Hasse diagram for the
higher Stasheff-Tamari order
on the triangulations of a cyclic 3-dimensional polytope with 7 vertices,
(produced by Jörg Rambau).
- the graph of all reduced words for the
longest element in the
rank 3 finite Coxeter groups, that is, the orthogonal symmetries
of these regular solids:
(produced by Rob Edman).
