Title: on the Lelong number of Whitney stratified sets

Abstract: the Lelong number (or density) may be considered 
as a counterpart of the notion of multiplicity (used in 
complex algebraic geometry) for real analytic and algebraic 
sets. 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.
