Title: Degree of non local connectedness

Abstract. For a given continuum \(X\) we assign a cardinal number or a symbol \(\infty\)  \(\tau(X)\) called degree of non local connectedness. The number \(\tau(X)\) 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
