Common Fixed Point Theorems for a Finite Family of Discontinuous and Noncommutative Maps

open access: yesFixed Point Theory and Applications, 2011
We study common fixed point theorems for a finite family of discontinuous and noncommutative single-valued functions defined in complete metric spaces.

Remarks on certain selected fixed point theorems

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2002
Fixed point theorems due to Lal et al. (1996) and Jungck (1988) are used to derive two common fixed point theorems involving six mappings in complete and compact metric spaces, respectively.

FIXED POINT THEOREM FOR MULTIFUNCTIONS

open access: yesDemonstratio Mathematica, 1984
This paper proves a fixed point theorem for multifunctions by the Ekeland variational principle. As an application a theorem of Lusternik is reobtained, but the argument seems not entirely correct. Using the author's notation, the following counterexample may be considered: \(X=Y\), \(H(x)=x\), \(u=x\), \(T=I\), \(x_ 0=0\). Then p is arbitrary positive,
