“…A classical theorem of Riemann says that any conditional convergent series of reals numbers can be rearranged to converge to any given real number or to diverge to +∞ or −∞. In other words, if (a n ) n is a conditional convergent series and r ∈ R ∪ {+∞, −∞}, there is a permutation π : N → N such that n a π(n) = r. In [18,34] is considered a property of ideals motivated by Riemann's theorem. Let us say that an ideal I has the property R, if for any conditionally convergent series n a n of real numbers and for any r ∈ R ∪ {+∞, −∞}, there is a permutation π : N → N such that n a π(n) = r and {n ∈ N : π(n) = n} ∈ I.…”

“…Similarly, I has property W, if for any conditionally convergent series of reals n a n , there exists A ∈ I such that the restricted series n∈A a n is still conditionally convergent. In [34] it is studied similar properties but for series of vectors in R 2 . [34]) Suppose that (i) I has the R property; (ii) n a n is a conditionally convergent series of reals; (iii) n b n is divergent and all b n are positive reals.…”
