A fake projective space is a smooth complex projective algebraic variety which is uniformized by the unit ball in $\mathbb C^n$ and whose Betti numbers are the same as that of $\mathbb P^n_{\mathbb{C}}$. The first example of a fake projective plane ($n=2$) was constructed by David Mumford using p-adic uniformization. Last year, in a joint work with Sai Kee Yeung we constructed twelve distinct classes of fake projective planes. In a recent work with him we show that there are four 4-dimensional arithemtically defined fake projective spaces and none in higher dimension which are arithmetically defined. In the talk I will present a survey of these results, open problems, and describe the techniques used to prove our results.
