Authors
-------------------------------------------------------------------------------

Fredrik Johansson is the main author. The project was started in 2012
as a numerical extension of FLINT, and the initial design was heavily based
on FLINT 2.0 (with particular credit to Bill Hart and Sebastian Pancratz).

The following authors have developed major new features.

* Pascal Molin - Dirichlet characters, Dirichlet L-functions, discrete logarithm computation
* Alex Griffing - sinc function, matrix trace, improved matrix squaring, boolean matrices, improved structured matrix exponentials, Cholesky decomposition, miscellaneous patches

Several people have contributed patches, bug reports, or substantial feedback.
This list (ordered by time of first contribution) is probably incomplete.

* Bill Hart - build system, Windows 64 support, design of FLINT
* Sebastian Pancratz - divide-and-conquer polynomial composition algorithm (taken from FLINT)
* The MPFR development team - Arb includes two-limb multiplication code taken from MPFR
* Jonathan Bober - original code for Dirichlet characters, C++ compatibility fixes
* Yuri Matiyasevich - feedback about the zeta function and root-finding code
* Abhinav Baid - dot product and norm functions
* Ondřej Čertík - bug reports, feedback
* Andrew Booker - bug reports, feedback
* Francesco Biscani - C++ compatibility fixes, feedback
* Clemens Heuberger - work on Arb interface in Sage, feedback
* Marc Mezzarobba - work on Arb interface in Sage, bug reports, feedback
* Ricky Farr - convenience functions, feedback
* Marcello Seri - fix for static builds on OS X
* Tommy Hofmann - matrix transpose, comparison, other utility methods, Julia interface
* Alexander Kobel - documentation and code cleanup patches
* Hrvoje Abraham - patches for MinGW compatibility
* Julien Puydt - soname versioning support
* Jeroen Demeyer - patch for major bug on PPC64
* Isuru Fernando - continuous integration setup, support for cmake and MSVC builds
* François Bissey - build system patches

Funding
-------------------------------------------------------------------------------

From 2012 to July 2014, Fredrik's work on Arb was supported by
Austrian Science Fund FWF Grant Y464-N18 (Fast Computer Algebra
for Special Functions).
During that period, he was a PhD student (and briefly a postdoc) at
RISC, Johannes Kepler University, Linz, supervised by Manuel Kauers.

From September 2014 to October 2015, Fredrik was a postdoc at
INRIA Bordeaux and Institut de Mathématiques de Bordeaux,
in the LFANT project-team headed by Andreas Enge. During that period,
Fredrik's work on Arb was supported
by ERC Starting Grant ANTICS 278537 (Algorithmic Number Theory in
Computer Science) http://cordis.europa.eu/project/rcn/101288_en.html
Since October 2015, Fredrik is a CR2 researcher in the LFANT team,
funded by INRIA.
