On Normality in Soft Topological Spaces

The concept Soft Sets was introduced by Molodtsov in the year 1999 to deal with problems of incomplete information. Due to the parameterization tools the used soft sets enhanced applicability of various generalizations of crisp sets. Soft topological space was formulated by Shabir et. al. and Cagman et al. separately in 2011. In this paper we study normality and related problems in soft topological spaces. We prove a form of Urysohn Lemma in this setting.
