TL;DR: In this article, an interpolation formula for functions in the Hardy space on the right-half plane was proposed and proved to converge in norm and pointwise under a general condition.
Abstract: We introduce an interpolation formula for functions in the Hardy space on the right-half plane and prove its convergence in norm and pointwise under very general condition. We also obtain an inverse formula for the Laplace transform from data on a finite interval.

TL;DR: In this paper, a generalized convolution was used to solve a class of Toeplitz plus Hankel integral equations, and also a system of integro-differential equations.
Abstract: from Lp(R+) to Lq(R+), (1 6 p 6 2, p−1 + q−1 = 1) with the help of a generalized convolution and prove Watson’s and Plancherel’s theorems. Using generalized convolutions a class of Toeplitz plus Hankel integral equations, and also a system of integro-differential equations are solved in closed form. Mathematics Subject Classification: 44A05, 44A35

TL;DR: Watson's and Plancherel's theorems are obtained on integral transforms of the form f ( x) ↦ g ( x ) = ( 1 − d 2 / d x 2) .
Abstract: Integral transforms of the form f ( x ) ↦ g ( x ) = ( 1 − d 2 / d x 2 ) { ∫ 0 ∞ k 1 ( y ) [ f ( | x + y − 1 | ) + f ( | x − y + 1 | ) − f ( x + y + 1 ) − f ( | x − y − 1 | ) ] d y + ∫ 0 ∞ k 2 ( y ) [ f ( x + y ) + f ( | x − y | ) ] d y } from L p ( ℝ + ) to L q ( ℝ + ) , ( 1 ≤ p ≤ 2 , p − 1 + q − 1 = 1 ) are studied. Watson's and Plancherel's theorems are obtained.

TL;DR: In this paper, the operational properties of two integral transforms of Fourier type were presented, and the formulation of convolutions for those transforms were derived and applied to linear partial differential equations and an integral equation with mixed Toeplitz-Hankel kernel.
Abstract: In this paper we present the operational properties of two integral transforms of Fourier type, provide the formulation of convolutions, and obtain eight new convolutions for those transforms. Moreover, we consider applications such as the construction of normed ring structures on \(L_{1}({\mathbb{R}})\), further applications to linear partial differential equations and an integral equation with a mixed Toeplitz-Hankel kernel.
