Kontorovich-Lebedev-Fourier space for de Sitter correlators
In this work, we build a novel frequency-momentum space for (d + 1)-dimensional de Sitter (dS) correlators from first principles. This construction follows directly from the decomposition into unitary irreducible representations (UIRs) of the spacetime ...

Abstract An initial‐boundary value problem for the transient electromagnetic field in the presence of a complicated‐shape scatterer is studied. The considered biconical zero‐thickness and perfectly conducting surface with periodic longitudinal slots has many special cases, each of which is of separate practical interest.

We study the asymptotic behavior of the free partition function in the t → 0+ limit for a diffusion process which consists of d‐independent, one‐dimensional, symmetric, 2s‐stable processes in a hyperrectangular cavity K⊂Rd with an absorbing boundary.

The polyconvolution with the weight function γ of three functions f, g, and h for the integral transforms Fourier sine (Fs), Fourier cosine (Fc), and Kontorovich‐Lebedev (Kiy), which is denoted by ∗γ(f,g,h)(x), has been constructed. This polyconvolution satisfies the following factorization property Fc(∗γ(f,g,h))(y)=sin y(Fsf)(y)·(Fcg)(y)·(Kiyh)(y ...

Central factorials under the Kontorovich–Lebedev transform of polynomials
In this paper, we show that slight modifications of the Kontorovich–Lebedev (KL) transform lead to an automorphism of the vector space of polynomials.

The Kontorovich-Lebedev transform as a map between d-orthogonal polynomials
A slight modification of the Kontorovich–Lebedev transform is an auto-morphism on the vector space of polynomials. The action of this inline image-transform over certain polynomial sequences will be under discussion, and a special attention will be given

On the use of Kontorovich-Lebedev transform in electromagnetic diffraction by an impedance cone
We consider the boundary-value problem for the Helmholtz equation connected with an infinite circular cone with an impedance boundary on its face. The scheme of solution includes applying the Kontorovich-Lebedev (KL) transform to reduce the problem to ...
