Fixed Point Theory and Applications 2013, 2013:223  doi:10.1186/1687-1812-2013-223

Published: 22 August 2013


In this paper we introduce the notion of probabilistic G-contraction and establish some fixed point theorems in such settings. Our results generalize/extend some recent results of Jachymski and Sehgal and Bharucha-Reid. Consequently, we obtain fixed point results for <a onClick="popup('http://www.fixedpointtheoryandapplications.com/content/2013/1/223/mathml/M1','MathML',630,470);return false;" target="_blank" href="http://www.fixedpointtheoryandapplications.com/content/2013/1/223/mathml/M1">View MathML</a>-chainable PM-spaces and for cyclic operators.
