p-Adic Square Root Function and p-Adic Light-cone
Abstract
The argument of the article demonstrates that the extension allowing square roots of ordinary p-adic numbers is 4-dimensional for p < 2 and 8-dimensional for p = 2. The region of convergence of the p-adic square root function can be regarded as the counterpart of light-cone.
