Subject: Petition in support of the IMA

Dear colleagues,

You may be aware that the NSF has recently decided not to renew
funding to the Institute for Mathematics and its Applications at the
University of Minnesota.

Here is an open letter to the NSF communicating the importance of the
IMA to many in our community:

If you would like to become a signatory to this, please follow this
link above. You may see a screen requesting a donation to the

Subject: INTLAB Version 9 for Matlab and Octave

Version 9 of INTLAB, the Matlab toolbox for Reliable Computing, is now
available for Matlab and Octave on

Given a numerical problem, INTLAB delivers verified bounds for the
solution together with a proof of existence and possibly
uniqueness. Correctness includes all procedural, possible
discretization and rounding errors as well as I/O. The input data may
be afflicted with tolerances.

INTLAB comprises of several separate toolboxes including automatic
differentiation (gradients, Hessians, Taylor expansion, slopes),
affine arithmetic etc. together with problem solving routines for
linear/nonlinear dense/sparse systems, (generalized) eigenvalue
problems etc.

For Octave the INTLAB package is self-contained including Octave
Version 3.8.2.

Mathematics of Lattices and Cybersecurity
April 21-24, 2015
ICERM, Brown University, USA

Lattices are abstractly very simple objects, yet their concrete
realizations contain beautifully intricate problems that are
stubbornly difficult even in low dimensions. For example, our present
day understandings of densest lattice packings and reduction theory
are still plagued with large gaps.

In the 1970's and 1980's lattices entered the world of cryptography as
tools used to break certain crypto systems, particularly those based
on the subset sum problem, and since the 1990's they have become
increasingly important in the building of other types of crypto
systems (thanks to the difficulty in the underlying
mathematics). Their significance has recently been bolstered by
average-case complexity bounds and their present resistance to quantum
computing attacks.

Currently the theory of lattices is a lively research topic among
mathematicians, computer scientists, and experts in
cybersecurity. However, to this date, there has been little to no
interaction between these communities. The goal of this workshop is to
stimulate activity between these different groups interested in
lattice problems. Topics to be covered include, but are not restricted
to, recent results on densest lattice packings, the geometry of
lattice moduli space and its connections with automorphic forms and
algebraic number theory, cryptographic applications of lattices, and
the state of the art of lattice reduction in high dimensions.
