On σ -porous sets in abstract spaces

L. Zajíček

Abstract and Applied Analysis, 2005, vol. 2005, 1-26

Abstract:

The main aim of this survey paper is to give basic information about properties and applications of σ - porous sets in Banach spaces (and some other infinite-dimensional spaces). This paper can be considered a partial continuation of the author's 1987 survey on porosity and σ -porosity and therefore only some results, remarks, and references (important for infinite-dimensional spaces) are repeated. However, this paper can be used without any knowledge of the previous survey. Some new results concerning σ -porosity in finite-dimensional spaces are also briefly mentioned. However, results concerning porosity (but not σ -porosity) are mentioned only exceptionally.
