Title: About a particular measure on the square

Abstract. Assuming the existence of Sierpiński set we construct a measure on some $$\sigma$$-field of subsets of the square which is perfect but not compact. This construction in 2001 answered Fremlin's question. We will describe open problems connected to this field.
