% Example of how to write the authors's data when the  %
% talk has more than one author                        %
% This option is used by providing separate commands   %
% \author and \address and, optionally,                %
% \email and \urladdr FOR EVERY AUTHOR                 %
% The real speaker must be marked by using             %
% the command \speaker instead of \author              %
% The command \address MUST NOT have breaking lines \\ %

In this work we complete the proof of the following theorem:  
Let $f$ be a continuous function defined on a closed interval $[a,b]$. Assume
$f(a)f(b)<0$. Then there exists $c\in(a,b)$ such that $f(c)=0$.
