KW - Beurling-Ahlfors extension, first variation, harmonic map.
AB - <p style="text-align: justify;">In this paper, we study the Beurling-Ahlfors extensions and prove two
results. The first variation of the Beurling-Ahlfors extension is not always harmonic;
the Beurling-Ahlfors extension of a quasi-symmetric mapping is not always harmonic.</p>
