Abstract: We prove that subparacompact mappings inversely preserve 2-subparacompactness. As some applications of the above result, we obtain that both perfect mappings and closed Lindelof regular mappings inversely preserve 2-subparacompactness, which answer a question on 2-subparacompactness posed by Qu and Yasui affirmatively. Also we give a counterexample to show that closed Lindelof mappings do not inversely preserve 2-subparacompactness.

Keywords: 2-subparacompactness; subparacompact mapping; closed Lindelof mapping

Classification (MSC2000): 54B05; 54C10; 54D10; 54D20
