Abstract
</center>
</b>
</p>

    <p>
The cubic convergence of a method inspired by a Hummel and Seebeck for solving variational inclusions, has been showed when the second order Fr&eacute;chet derivative of some function <i>f</i> satisfies a Lipschitz condition. Here, we prove the superquadratic convergence of this method whenever this second order Fr&eacute;chet derivative satisfies a Hölder condition.

Resumen
</center>
</b>
</p>

    <p>
La convergencia c&uacute;bica de un m&eacute;todo de Hummel y Seebeck para resolver inclusiones variacionales ha sido probado cuando la derivada de Fr&eacute;chet de segundo orden de alguna funci&oacute;n <i>f</i> satisface una condici&oacute;n de Lipschitz. Aqu&iacute; probamos la convergencia supercuadr&aacute;tica de este m&eacute;todo siempre que esta derivada de Fr&eacute;chet de segundo orden satisfaga una condici&oacute;n de Hölder.
