Corrigendum to a Category Analogue of The Generalization of Lebesgue Density Topology

The notion of A_I -density point introduced in Wojdowski, W. A topology stronger than the Lebesgue density topology, in: Real Functions, Density Topology and Related Topics, Łódź Univ. Press, 2011, pp. 73-80 [WO1]. leads to the operator Φ_AI (A) which is not a lower density operator. We present a counterexample giving a corrected definition which should be used in [WO1] to keep all results valid.
