THE SOLUTION OF EULER-CAUCHY EQUATION EXPRESSED BY DIFFERENTIAL OPERATOR USING LAPLACE TRANSFORM

open access: yes, 2013
It is well known fact that the Laplace transform is useful in solving linear ordinary differential equations with constant coefficients such as free/forced oscillations, but in the case of differential equation with variable coefficients is not. In here,

SOLVING FRACTIONAL INTEGRO DIFFERENTIAL EQUATIONS BY HOMOTOPY ANALYSIS TRANSFORM METHOD

open access: yes, 2016
In this paper, we introduce an analytical method, which so called the homotopy analysis transform method (HATM) which is a combination of HAM and Laplace decomposition method (LDM).

Existence, uniqueness and exponential boundedness of global solutions to delay fractional differential equations [PDF]

open access: yesMediterr. J. Math. 14 (2017), 2017
Under a mild Lipschitz condition we prove a theorem on the existence and uniqueness of global solutions to delay fractional differential equations. Then, we establish a result on the exponential boundedness for these solutions.

Existence and approximation of solutions of some first order iterative differential equations

open access: yes, 2010
Existence theorems for some iterative differential equations as well as convergence theorems for a fixed point iterative method designed to approximate these solutions, are proved under weaker conditions than those due to A.

A uniqueness result on ordinary differential equations with singular coefficients [PDF]

open access: yesarXiv, 2008
We consider the uniqueness of solutions of ordinary differential equations where the coefficients may have singularities. We derive upper bounds on the the order of singularities of the coefficients and provide examples to illustrate the results.

FLOW WITH $A_{\infty }(\mathbb{R})$ DENSITY AND TRANSPORT EQUATION IN $\text{BMO}(\mathbb{R})$

open access: yesForum of Mathematics, Sigma, 2019
We show that, if $b\in L^{1}(0,T;L_{\operatorname{loc}}^{1}(\mathbb{R}))$ has a spatial derivative in the John–Nirenberg space $\operatorname{BMO}(\mathbb{R})$, then it generates a unique flow $\unicode[STIX]{x1D719}(t,\cdot )$ which has an $A_{\infty }(\

Exponential ergodicity for SDEs with jumps and non-Lipschitz coefficients [PDF]

open access: yesarXiv, 2012
In this paper we show irreducibility and the strong Feller property for transition probabilities of stochastic differential equations with jumps and monotone coefficients. Thus, exponential ergodicity and the spectral gap for the corresponding transition semigroups are obtained.

Existence and dimension of the set of mild solutions to semilinear fractional differential inclusions

open access: yes, 2012
This article studies the existence and dimension of the set for mild solutions of semilinear fractional differential inclusions. We recall and prove some new results on multivalued maps to establish our main results.MSC 2010: 34A12; 34A40.

On second-order linear Stieltjes differential equations with non-constant coefficients

open access: yesOpen Mathematics
In this work, we define the notions of Wronskian and simplified Wronskian for Stieltjes derivatives and study some of their properties in a similar manner to the context of time scales or the usual derivative.
