“…The Fourier transforms in S ′ and D ′ are introduced by Gelfand and Shilov (1964). S ′ is the dual of the space S , which is the space of all infinitely differentiable functions which, together with their derivatives approach zero more rapidly than any power of 1/|x| as |x| → ∞ (Gelfand and Shilov, 1964, p.16).…”
Abstract. This paper deals with the investigation of a closed form solution of a generalized fractional reaction-diffusion equation. The solution of the proposed problem is developed in a compact form in terms of the H-function by the application of direct and inverse Laplace and Fourier transforms. Fractional order moments and the asymptotic expansion of the solution are also obtained.

“…As usual (see, e.g., [3], §I.3), the integral admits a meromorphic continuation to the whole plane (μ 1 , μ 2 ) ∈ C 2 with poles at μ 1 − μ 2 = 0, 1, 2, …. The operators A μ 1 ,ε 1 ;μ 2 ,ε 2 are intertwining, Discrete series.…”

“…Notice that canonical overgroups exist for all 10 series of real classical groups. 3 Moreover overgroups exist for all 52 series of classical semisimple symmetric spaces G/H , see [8,15], see also [18], Addendum D.6. So the problem makes sense for all classical symmetric spaces.…”

We define a kind of 'operational calculus' for the Fourier transform on the group GL 2 (R). Namely, GL 2 (R) can be regarded as an open dense chart in the Grassmannian of 2-dimensional subspaces in R 4 . Therefore the group GL 4 (R) acts in L 2 on GL 2 (R). We transfer the corresponding action of the Lie algebra gl 4 to the Plancherel decomposition of GL 2 (R), the algebra acts by differential-difference operators with shifts in an imaginary direction. We also write similar formulas for the action of gl 4 ⊕ gl 4 in the Plancherel decomposition of GL 2 (C).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
