Popis:	We consider the linear span S of the functions t a k (with some a k > 0 ) in weighted L 2 spaces, with rather general weights. We give one necessary and one sufficient condition for S to be dense. Some comparisons are also made between the new results and those that can be deduced from older ones in the literature.
