Connections between some measures of non-compactness and associated operators.

José M. Ayerbe Toledano, Tomás Domínguez Benavides, Genaro López Acedo (1990)

Extracta Mathematicae

Similarity:

Some relationships between the Kuratowski's measure of noncompactness, the ball measure of noncompactness and the δ-separation of the points of a set are studied in special classes of Banach spaces. These relations are applied to compare operators which are contractive for these measures.

Completely mixing maps without limit measure

Gerhard Keller (2004)

Colloquium Mathematicae

Similarity:

We combine some results from the literature to give examples of completely mixing interval maps without limit measure.

Common fixed points for commuting and compatible maps

Ismat Beg, Akbar Azam (1996)

Discussiones Mathematicae, Differential Inclusions, Control and Optimization

Similarity:

Fixed point theorems of multivalued hybrid contractions and Meir-Keeler type multivalued maps are obtained in a metric space. Our results generalize corresponding results of Aubin and Siegel, Dube, Dube and Singh, Hadzic, Iseki, Jungck, Kaneko, Nadler, Park and Bae, Reich, Ray and many others.
