We study the properties of category density topology of the plane generatedby a restricted convergence in the category of double sequences of characteristicfunctions{Â((n,m)·(A−(x0,y0)))\([−1,1]×[−1,1])}n,m2Nand more interesting topology generated by a strict convergence in the category of thesame sequences, which is a natural modification of a previous one. Similar problemsfor measure density were considered in [FW].
