Numerical Approximation of Fractional-Order Volterra Integrodifferential Equation
Journal of Function Spaces, 2020 Laplace transform is a powerful tool for solving differential and integrodifferential equations in engineering sciences. The use of Laplace transform for the solution of differential or integrodifferential equations sometimes leads to the solutions in ...

Deformable Laplace transform and its applications
Nonlinear Engineering, 2023 Recently, the deformable derivative and its properties have been introduced. In this work, we have investigated the concept of deformable Laplace transform (DLT) in more detail. Furthermore, some classical properties of the DLT are also included.

Discrete dipole approximation in time domain through the Laplace transform [PDF]
, 2013 We present a form of the discrete dipole approximation for electromagnetic scattering computations in time domain. We show that the introduction of complex frequencies, through the Laplace transform, significantly improves the computation time.

Algebraic inversion of the Laplace transform
Computers & Mathematics with Applications, 2005 AbstractA new algebraic scheme for inverting Laplace transforms of smooth functions is presented. Expansion of the Laplace transform F(s) in descending powers of s is used to construct the Taylor series of the corresponding time function f(t). This is done through entirely algebraic evaluations of F(s) at symmetric points around circles in the complex ...

A new construction of the Clifford-Fourier kernel [PDF]
, 2016 In this paper, we develop a new method based on the Laplace transform to study the Clifford-Fourier transform. First, the kernel of the Clifford-Fourier transform in the Laplace domain is obtained.

Regularized Inversion of Noisy Laplace Transforms
Advances in Applied Mathematics, 1994 AbstractIn this paper we construct a sequence of regularized inverses of the Laplace transform by relating this transform to a convolution operator for functions on the group of the positive real numbers with multiplication. Estimation of the mixing distribution, when a mixture of exponential distributions is observed, is an example.

, 2015 The Laplace transforms of the transition probability density and distribution functions for the Ornstein-Uhlenbeck process contain the product of two parabolic cylinder functions, namely D_{v}(x)D_{v}(y) and D_{v}(x)D_{v-1}(y), respectively.
