AB - <p style="text-align: justify;">In this article, we generalize Chebyshev&#39;s maximum principle to several
variables. Some analogous maximum formulae for the special integration functional
are given. A sufficient condition of the existence of Chebyshev&#39;s maximum principle
is also obtained.</p>
