Fixed singular point
From HandWiki
A common singular point $ z _ {0} $ of all solutions $ w $ of a differential equation $ F ( z, w, w ^ \prime ) = 0 $( where $ F $ is an analytic function), regarded as functions $ w ( z) $ of a complex variable $ z $, the initial conditions of which range over a certain domain in the $ ( z, w) $- space.
