The quadratic isoperimetric inequality for mapping tori of free group automorphisms II: The general case
If F is a finitely generated free group and \phi is an automorphism of F then
the mapping torus of \phi admits a quadratic isoperimetric inequality.
This is the third and final paper in a series proving this theorem. The first
two were math.GR/0211459 and math.GR/0507589.Comment: 73 page
Fitting quotients of finitely presented abelian-by-nilpotent groups
We show that every finitely generated nilpotent group of class 2 occurs as
the quotient of a finitely presented abelian-by-nilpotent group by its largest
nilpotent normal subgroup.Comment: This second version takes into account the suggestions by the

Telescope Time Without Tears: A Distributed Approach to Peer Review
The procedure that is currently employed to allocate time on telescopes is
horribly onerous on those unfortunate astronomers who serve on the committees
that administer the process, and is in danger of complete collapse as the
number of applications steadily increases. Here, an alternative is presented,
whereby the task is distributed around the astronomical community, with a
suitable mechanism design established to steer the outcome toward awarding this
precious resource to those projects where there is a consensus across the
community that the science is most exciting and innovative.Comment: 9 pages, accepted for publication in Astronomy & Geophysic
