Abstract
The Large Scale Structure in the galaxy distribution is
investigated using Data Release 1 of the Sloan Digital
Sky Survey. Using the Minimal Spanning Tree technique we have
extracted sets of filaments, of wall-like structures, of galaxy
groups, and of rich clusters from this unique sample. The physical
properties of these structures were then measured and compared with
the statistical expectations based on Zel'dovich theory.
Key words: cosmology: large-scale structure of the Universe -- surveys

| What is OpenURL? |
The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.
- If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
- You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
- You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
