The Lelong number of a real analytic germ A (at 0) is defined as the limit (as r goes to zero) of the volume of A intersected with a ball of radius r (centred at 0) divided by the volume of this ball. I will explain that it varies continuously along the strata of a Whitney stratification. -------------------------------------------------------- Geometry Seminar Web Site: http://www.maths.usyd.edu.au/u/SemConf/Geometry/index.html
