arXiv script is a program written in the python programming language that accesses information on papers from the arXiv. It can access title, author, abstract, comments and journal reference records. It can also download the paper's PDF, PS or source. Although originally written for the GNU/Linux command line, the code should be portable enough to run on any operating system with a python interpreter.



installation on a GNU/Linux system

The script requires the python interpreter to be installed on your system. This is automatically installed on most GNU/Linux distributions, but check it is there by typing


at the command line and see what happens.

If python is present download and run it by typing

python hep-th/9711200


The only accepted inputs are the usual arXiv references

python hep-th/9711200
python 0705.0303

If no options are specified all possible outputs will be displayed

The Large N Limit of Superconformal Field Theories and Supergravity
Juan M. Maldacena
We show that the large $N$ limit of certain conformal field theories in
various dimensions include in their Hilbert space a sector describing
supergravity on the product of Anti-deSitter spacetimes, spheres and other
compact manifolds. This is shown by taking some branes in the full M/string
theory and then taking a low energy limit where the field theory on the brane
decouples from the bulk. We observe that, in this limit, we can still trust the
near horizon geometry for large $N$. The enhanced supersymmetries of the near
horizon geometry correspond to the extra supersymmetry generators present in
the superconformal group (as opposed to just the super-Poincare group). The 't
Hooft limit of 4-d ${\cal N} =4$ super-Yang-Mills at the conformal point is
shown to contain strings: they are IIB strings. We conjecture that
compactifications of M/string theory on various Anti-deSitter spacetimes are
dual to various conformal field theories. This leads to a new proposal for a
definition of M-theory which could be extended to include five non-compact

To see all the options access the help page

tom@fyodor:~$ python -h

python reference [ -htabcjdps ] [ --help ]
"reference" must be a standard arXiv reference, e.g. hep-th/9711200, 0705.0303.
-h, --help
displays this help message
displays the title
displays the author(s)
displays the aBstract
displays the comments

downloads the PDF
downloads the PS
downloads the source file

Each item can be specified individually with switches, e.g. -t for title, -a for authors, -b for aBstract, -c for comments. For example

technical details

The code is very modular so it is easy to write your own programs using the functions defined in Just import the functions in with import arxiv.
