Title: Degree of non local connectedness

Abstract. For a given continuum X we assign a cardinal number or a symbol   τ(X) called degree of non local connectedness. The number τ(X) cannot be increased by a continuous image; we show theorems about cartesian products, hyperspaces etc. Based on an article by Janusz J. Charatonik and Włodzimierz J. Charatonik
