**“arXiv”** opposite is **“viXra”.**

The former **“arXiv”** is administered by Cornell University for Math paper publishing online. The traditional math journals would take 2 years to review and publish.

The Russian Mathematician **G. Perelman** was fed up of the long and bureaucratic review process, sent his proof of the 100-year-old unsolved “**Poincaré Conjecture”** to **arXiv** site. Later it was recognized to be correct, but Perelman refused to accept the **Fields Medal** and $1 million **Clay Prize**.

The new site **“viXra”** is open to anybody in the world, while “arXiv” is still restricted to academics.
