The notion of bi-inner product functionals $P(f,g) = sumlimits_n{<f,f_n> <g,g_n>}$ generated by two Bessel sequences {f n } and {g n } of functions from L 2 was
A set is called regular if its Hausdorff dimension and upper box-counting dimension coincide.In this paper,we prove that the random self-conformal set is regula
The authors establish the boundedness on homogeneous weighted Herz spaces for a large class of rough grals and the rough R. Fefferman singular integral operator
We will define and characterize e-weakly Chebyshev subspaces of Banach spaces. We will prove that all closed subspaces of a Banach space X are e-weakly Chebyshe
