We shall say that a set (Esubset C_{n}(Omega)) has a covering ({r_{k}, R_{k}}) if there exists a sequence of balls ({B_{k}}) with centers in (C_{n}(Omega)) such that (Esubsetbigcup_{k=1}^{infty} B_{k}), where (r_{k}) is the radius of (B_{k}) and (R_{k}) is the distance from the origin to the center of (B_{k}).
We shall say that a set (Esubset C_{n}(Omega)) has a covering ({r_{j}, R_{j}}) if there exists a sequence of balls ({B_{j}}) with centers in (C_{n}(Omega)) such that (Esubsetbigcup_{j=1}^{infty} B_{j}), where (r_{j}) is the radius of (B_{j}) and (R_{j}) is the distance between the origin and the center of (B_{j}).
We shall say that a set E ⊂ H has a covering { r j, R j } if there exists a sequence of balls { B j } with centers in H such that E ⊂ ⋃ j = 0 ∞ B j, where r j is the radius of B j and R j is the distance between the origin and the center of B j.
We shall say that a set E ⊂ C n has a covering { r j, R j } if there exists a sequence of balls { B j } with centers in C n such that E ⊂ ⋃ j = 0 ∞ B j, where r j is the radius of B j and R j is the distance from the origin to the center of B j.
We shall say that a set (Hsubset C_{n}(Omega)) has a covering ({r_{j}, R_{j}}) if there exists a sequence of balls ({B_{j}}) with centers in (C_{n}(Omega)) such that (Hsubsetbigcup_{j=0}^{infty} B_{j}), where (r_{j}) is the radius of (B_{j}) and (R_{j}) is the distance from the origin to the center of (B_{j}).
We shall say that a set (Esubset C_{n}(Omega)) has a covering ({r_{j}, R_{j}}) if there exists a sequence of balls ({B_{j}}) with centers in (C_{n}(Omega)) such that (Esubsetbigcup_{j=0}^{infty} B_{j}), where (r_{j}) is the radius of (B_{j}) and (R_{j}) is the distance from the origin to the center of (B_{j}).
