On the Lebedev transformation in Hardy's spaces
نویسنده
چکیده
We establish the inverse Lebedev expansion with respect to parameters and arguments of the modified Bessel functions for an arbitrary function from Hardy’s space H2,A, A> 0. This gives another version of the Fourier-integral-type theorem for the Lebedev transform. The result is generalized for a weighted Hardy space Ĥ2,A ≡ Ĥ2((−A,A);|Γ(1+Rez+iτ)|2dτ), 0 < A < 1, of analytic functions f(z),z = Rez+ iτ , in the strip |Rez| ≤ A. Boundedness and inversion properties of the Lebedev transformation from this space into the space L2(R+;x−1dx) are considered. When Rez = 0, we derive the familiar Plancherel theorem for the Kontorovich-Lebedev transform.

Thomas Hardy's Under the Greenwood Tree : An Althusserian Perspective
With the beginning of the 19th century, England entered into a transitional period. Sociologists believe that in each era of transformation, the ruling class tries to establish its own values, but some resistance to these new values is inevitable. Thomas Hardy's novels in general, and Under the Greenwood Tree specifically, are no exception. Based on these notions, this paper tries to interpret ...
متن کاملFrom the Lorentz Transformation Group in Pseudo-Euclidean Spaces to Bi-gyrogroups
The Lorentz transformation of order $(m=1,n)$, $ninNb$, is the well-known Lorentz transformation of special relativity theory. It is a transformation of time-space coordinates of the pseudo-Euclidean space $Rb^{m=1,n}$ of one time dimension and $n$ space dimensions ($n=3$ in physical applications). A Lorentz transformation without rotations is called a {it boost}. Commonly, the ...
متن کاملHarmonic potentials for quaternionic symmetric σ-models
We construct N = 2 superspace Lagrangians for quaternionic symmetric σmodels G/H × Sp(1), or equivalently, quaternionic potentials for these symmetric spaces. They are homogeneous H invariant polynomials of order 4 which are similar to the quadratic Casimir operator of H. The construction is based on an identity for the structure constants specific for quaternionic symmetric spaces. † On leave ...
متن کاملSome Observations on Dirac Measure-Preserving Transformations and their Results
Dirac measure is an important measure in many related branches to mathematics. The current paper characterizes measure-preserving transformations between two Dirac measure spaces or a Dirac measure space and a probability measure space. Also, it studies isomorphic Dirac measure spaces, equivalence Dirac measure algebras, and conjugate of Dirac measure spaces. The equivalence classes of a Dirac ...
متن کاملLp-BOUNDEDNESS OF THE GENERAL INDEX TRANSFORMS
Abstract We establish the boundedness properties in Lp for a class of integral transformations with respect to an index of hypergeometric functions. In particular, by using the RieszThorin interpolation theorem we get the corresponding results in Lp(R+), 1 ≤ p ≤ 2 for the Kontorovich-Lebedev, Mehler-Fock and Olevskii index transforms. An inversion theorem is proved for general index transformat...
