Once More on the Lefschetz Fixed Point Theorem

Lech Górniewicz, Mirosław Ślosarski (2007)

Bulletin of the Polish Academy of Sciences. Mathematics

An abstract version of the Lefschetz fixed point theorem is presented. Then several generalizations of the classical Lefschetz fixed point theorem are obtained.

Selections and near-selections in metric linear spaces without local convexity

Tadeusz Dobrowolski, Jan van Mill (2006)

Fundamenta Mathematicae

We characterize the AR property in convex subsets of metric linear spaces in terms of certain near-selections.

The compact extension property: the role of compactness

Jos Bijl, Jan van Mill (1991)

Commentationes Mathematicae Universitatis Carolinae

We consider separable metrizable topological spaces. Among other things we prove that there exists a non-contractible space with the compact extension property and we prove a new version of realization of polytopes for $ANR$ ’s.

We prove that a metric space is an ANR if, and only if, every open subset of X has the homotopy type of a CW-complex.
