Functional Analysis and Its Applications, 1996
This note has discussed three fixed point theorems for mappings \(T:H\times H\to H\), where \(H\) is a suitable subset of a metric or normed linear space, satisfying certain conditions. Only indications of the proofs are given. The first two theorems are proved with the help of a theorem due to \textit{M. Edelstein} [J. Lond. Math. Soc. 37, 74-79 (1962;

We prove a fixed point theorem for the action of a Lie group \(G\) acting isometrically on a non-negatively curved Riemannian manifold with principal orbits which are isotropy irreducible homogeneous spaces. We refine our result when the curvature is positive and give a possible application to the study of immersions of homogeneous spaces into spheres.

Some Fixed Point Theorems [PDF]
The Annals of Mathematics, 1951 where f, p are continuous, g satisfies a Lipschitz condition, p(t) has period 1, and g(t)/I ? 1 for large t at any rate. Our choice of hypotheses and the main lines of our investigations have been dominated by what is significant in the theory of differential equations, but our results are concerned solely with sets of points and transformations of ...

In this paper we obtain a generalization of Matkowski’s fixed point theorem and Istrăţescu’s fixed point theorem concerning convex contractions. More precisely, given a complete b-metric space (X, d) we prove that every continuous function $$ f:X ...
