Corresponding to [27], some properties of S-closed subspaces and subsets -closed relative to a topological space are proved. Conditions under which mappings preserve certain -closed subspaces are investigated.
Relativamente al [27], sono provate alcune proprieta dei sottoinsiemi -chiusi di uno spazio topologico. Sono studiate delle condizioni mediante le quali le applicazioni conservano alcuni sottospazi -chiusi.
