# ArXiv script

(diff) ← Older revision | Latest revision (diff) | Newer revision → (diff)

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

python


at the command line and see what happens.

If python is present download arxiv.py and run it by typing

python arxiv.py hep-th/9711200


### usage

The only accepted inputs are the usual arXiv references

python arxiv.py hep-th/9711200
python arxiv.py 0705.0303

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
dimensions.

### technical details

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