%0 Journal Article %T A brief introduction to p-adic numbers %A Stephen Semmes %J Mathematics %D 2003 %I arXiv %X In this short survey we look at a few basic features of p-adic numbers, somewhat with the point of view of a classical analyst. In particular, with p-adic numbers one has arithmetic operations and a norm, just as for real or complex numbers. %U http://arxiv.org/abs/math/0301035v2
