On the Existence and Uniqueness of Solution to Fractional-Order Langevin Equation

Advances in Mathematical Physics, 2020
In this work, we give sufficient conditions to investigate the existence and uniqueness of solution to fractional-order Langevin equation involving two distinct fractional orders with unprecedented conditions (three-point boundary conditions including ...

EXISTENCE AND UNIQUENESS OF CHAIN LADDER SOLUTIONS

ASTIN Bulletin, 2015
AbstractThe cross-classified chain ladder has a number of versions, depending on the distribution to which observations are subject. The simplest case is that of Poisson distributed observations, and then maximum likelihood estimates of parameters are explicit.

On the existence and uniqueness of solutions of Möbius equations [PDF]

Transactions of the American Mathematical Society, 1993
A generalization of the Schwarzian derivative to conformal mappings of Riemannian manifolds has naturally introduced the corresponding overdetermined differential equation which we call the Möbius equation. We are interested in study of the existence and uniqueness of the solution of the Möbius equation.

Existence and uniqueness theorem for a solution of fuzzy differential equations

International Journal of Mathematics and Mathematical Sciences, 1999
By using the method of successive approximation, we prove the existence and uniqueness of a solution of the fuzzy differential equation x′(t)=f(t,x(t)),x(t0)=x0. We also consider an ϵ-approximate solution of the above fuzzy differential equation.

Existence and uniqueness of the Karcher mean on unital C⁎-algebras [PDF]

Journal of Mathematical Analysis and Applications, 2019
The Karcher mean on the cone $\Omega$ of invertible positive elements of the $C^*$-algebra $\mathcal{B}(E)$ of bounded operators on a Hilbert space $E$ has recently been extended to a contractive barycentric map on the space of $L^1$- probability ...

Existence and Uniqueness of Perturbation Solutions to DSGE Models [PDF]

, 2012
We prove that standard regularity and saddle stability assumptions for linear approximations are sufficient to guarantee the existence of a unique solution for all undetermined coefficients of nonlinear perturbations of arbitrary order to discrete time DSGE models.

Therapeutic Apheresis in Nigeria: A Multi‐Center Summary of Abstracts From the Inaugural Nigerian Society for Apheresis Scientific Meeting

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Therapeutic apheresis (TA) is an established treatment modality for hematologic, neurologic, and immunologic disorders, yet access remains severely limited in sub‐Saharan Africa. Donor apheresis, including platelet apheresis collection from healthy donors, represents an important complementary modality supporting blood product ...

Determination of a Nonlinear Coefficient in a Time-Fractional Diffusion Equation

Fractal and Fractional, 2023
In this paper, we study direct and inverse problems for a nonlinear time fractional diffusion equation. We prove that the direct problem has a unique weak solution and the solution depends continuously on the coefficient.
