This is an announcement for the paper "A note on curves equipartition"
by M. A. Lopez and S. Reisner.


Abstract: The problem of the existence of an equi-partition of a
curve in $\R^n$ has recently been raised in the context of computational
geometry. The problem is to show that for a (continuous) curve
$\Gamma : [0,1] \to \R^n$ and for any positive integer $N$, there
exist points $t_0=0<t_1<...<t_{N-1}<1=t_N$, such that
$d(\Gamma(t_{i-1}),\Gamma(t_i))=d(\Gamma(t_{i}),\Gamma(t_{i+1}))$
for all $i=1,...,N$, where $d$ is a metric or even a semi-metric
(a weaker notion) on $\R^n$. We show here that the existence of
such points, in a much broader context, is a consequence of Brower's
fixed point theorem.
