Differential transform method: A comprehensive review and analysis [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization, 2022
The complexity of solving differential equations in real-world applications motivates researchers to extend numerical methods. Among different numerical and semi-analytical methods for solving initial and boundary value problems, the differential ...

Initial Value Problems of Semilinear Supdiffusion Equations

open access: yesMathematics, 2020
We consider the existence of a mild solution of supdiffusion equations and obtain some results under some growth and noncompactness conditions of nonlinearity without coefficient restriction; and some new results for Ulam-Hyers-Rassias stability are ...

Rational Approximation Method for Stiff Initial Value Problems

open access: yesMathematics, 2021
While purely numerical methods for solving ordinary differential equations (ODE), e.g., Runge–Kutta methods, are easy to implement, solvers that utilize analytical derivations of the right-hand side of the ODE, such as the Taylor series method ...

On a SHOCKLEY-READ-HALL model for semiconductors [PDF]

open access: yesTheoretical and Applied Mechanics, 2013
The Shockley-Read-Hall model was introduced in 1952 to describe the statistics of recombination of holes and electrons in semiconductors occurring through the mechanism of trapping and we consider initial-boundary value problems with initial ...

On the Non-Local Boundary Value Problem from the Probabilistic Viewpoint

open access: yesMathematics, 2022
We provide a short introduction of new and well-known facts relating non-local operators and irregular domains. Cauchy problems and boundary value problems are considered in case non-local operators are involved.

New Algorithms for Dealing with Fractional Initial Value Problems

open access: yesAxioms, 2023
This work purposes to establish two small numerical modifications for the Fractional Euler method (FEM) and the Modified Fractional Euler Method (MFEM) to deal with fractional initial value problems.

Fully discrete hyperbolic initial boundary value problems with nonzero initial data [PDF]

open access: yes, 2014
The stability theory for hyperbolic initial boundary value problems relies most of the time on the Laplace transform with respect to the time variable. For technical reasons, this usually restricts the validity of stability estimates to the case of zero ...

Initial Value Problems and Signature Change [PDF]

open access: yes, 1995
We make a rigorous study of classical field equations on a 2-dimensional signature changing spacetime using the techniques of operator theory. Boundary conditions at the surface of signature change are determined by forming self-adjoint extensions of the

A new type of shooting method for nonlinear boundary value problems

open access: yesAlexandria Engineering Journal, 2013
In this article we introduce a new type of iterative method for initial value problems (IVPs). We enhance this method by using shooting techniques and interpolation for the boundary value problems. Our method is more accurate and applicable than built in

Optimal stability polynomials for numerical integration of initial value problems [PDF]

open access: yes, 2012
We consider the problem of finding optimally stable polynomial approximations to the exponential for application to one-step integration of initial value ordinary and partial differential equations.
