On Mappings Preserving a Family of Star BodiesGrzegorz SójkaWydzia{\l} Matematyki i nauk Informacyjnych, Politechnika Warszawska, Plac Politechniki 1, 00668 Warszawa, Polska; email: grzegorz.sojka@prioris.mini.pw.edu.plAbstract: The paper concerns the star mappings understood as topological embedding of $\mathbb{R}^{n}$ into itself preserving the class of bodies which are star shaped at point $0$. The main result is full characterization of star mappings (Theorem 2.8). At the end we give a solution of some related problem. Keywords: star set, star body, star mapping Classification (MSC2000): 52A30, 54C99, 54C05 Full text of the article:
