Using this method, Meijer’s G-function solutions are derived in cylindrical coordinate system for quantum particle in cylindrical can. All elementary functions and most of the special functions which are the solution of extensive problems in physics and engineering are special cases of Meijer’s G-functions.展开更多

Under the weak space satisfying both the geometrically doubling and reverse doubling condition, the authors prove that the generalized homogeneous Littlewood-Paley g-function gr (r ∈ [2, ∞)) is bounded from Hardy space H1(u) into L1(u). Moreover, the authors show that, if f ∈ RBMO(u), then [gr(f)]r is either infinite everywhere or finite almost everywhere, and in the latter case, [gr(f)]r belongs to RBLO(u) with the norm no more than ||f|| RBMO(u) multiplied by a positive constant which is independent of f. As a corollary, the authors obtain the boundedness of gr from RBMO(u) into RBLO(u). The vector valued Calderon-Zygmund theory over (X, d, u) is also established with details in this paper.展开更多
