corresponding univariate kernel which is bounded and symmetric, then
l() is non-negative,

The following definitions are due to Robinson (1988).

Definition (D1)   Yλ, λ1 is the class of even functions k: RR satisfying

uik(u)du=δi0      (i =0,1,K,λ-1),

R

k(u) = O ( (1 + uр+1+г )-1 ), for some ε > 0,

where δi is the Kronecker’s delta.
