Final-value problem for a weakly-coupled system of structurally damped waves

open access: yesElectronic Journal of Differential Equations, 2018
We consider the final-value problem of a system of strongly-damped wave equations. First of all, we find a solution of the system, then by an example we show the problem is ill-posed.

Modified quasi-reversibility method for final value problems in Banach spaces

open access: yesJournal of Mathematical Analysis and Applications, 2008
This paper presents a new version of the quasi-reversibility method for regularizing linear ill-posed problems. Its focus is on the stable approximate solution of final value problems \[ u^\prime(t)+Au(t)=0\quad (0 \leq t 0\) are discussed when \[ v_\alpha(t)^\prime+A_\alpha v_\alpha(t)=0 \quad (0 \leq t

Final value problem for fractional reaction-subdiffusion equations

open access: yesHPU2 Journal of Science: Natural Sciences and Technology
We investigate the existence of a mild solution to the final value problem for a class of fractional reaction-subdiffusion nonlinear equations, where the nonlinearity may take weak values. We want to demonstrate the unique existence of a mild solution by using the Banach fixed-point theorem.

On a final value problem for parabolic equation on the sphere with linear and nonlinear source

open access: yesAdvances in the Theory of Nonlinear Analysis and its Application, 2020
 Parabolic equation on the unit sphere arise naturally in geophysics and oceanography when we model a physical quantity on large scales. In this paper, we consider a problem of finding the initial state for backward parabolic problem on the sphere. This backward parabolic problem is ill-posed in the sense of Hadamard.

Characterization of the value function of final state constrainedcontrol problems with BV trajectories [PDF]

open access: yesCommunications on Pure and Applied Analysis, 2011
This paper aims to investigate a control problem governed by differential equations with Radon measure as data and with final state constraints. By using a known reparametrization method (by Dal Maso and Rampazzo [18]), we obtain that the value function can be characterized by means of an auxiliary control problem of absolutely continuous trajectories,

A uniqueness result for final boundary value problem of microstretch bodies

open access: yesThe Journal of Nonlinear Sciences and Applications, 2017
Summary: Main subject of this study is the final boundary value problem of a microstretch thermoelastic body. In fact, using an elementary transformation, this problem is reformulated as a known mixed problem with initial and boundary conditions. We prove some results of uniqueness of solutions avoiding any conservation law of energy.
