Comparison of proper shape and proper shape over finite coverings


Nikita Shekutkovski, Abdulla Buklla




The theory of proper shape over finite coverings, defined in [8], uses only finite coverings to compare noncompact spaces. In this paper we investigate the relations between this theory and the proper shape defined by Ball and Sherr in [3]. We show that if two spaces have same proper shape they belong to the same class in theory of proper shape over finite coverings, but the opposite doesn't hold in general.
