On a final value problem for a nonhomogeneous fractional pseudo-parabolic equation

open access: goldAlexandria Engineering Journal, 2020
In this paper, we are interested in finding the function u(t,x),(t,x)∈[0,T)×Ω from the final data u(T,x)=ϕ(x), satisfies a nonhomogeneous fractional pseudo-parabolic equation. The problem is stable for the cases σν, the problem is ill-posed (in the sense

Final Value Problem for Parabolic Equation with Fractional Laplacian and Kirchhoff’s Term [PDF]

open access: goldJournal of Function Spaces, 2021
In this paper, we study a diffusion equation of the Kirchhoff type with a conformable fractional derivative. The global existence and uniqueness of mild solutions are established. Some regularity results for the mild solution are also derived.

A Class of Well-Posed Parabolic Final Value Problems [PDF]

open access: green, 2020
This paper focuses on parabolic final value problems, and well-posedness is proved for a large class of these. The clarification is obtained from Hilbert spaces that characterise data that give existence, uniqueness and stability of the solutions.

Final Value Problems for Parabolic Differential Equations and Their Well-Posedness [PDF]

open access: goldAxioms, 2018
This article concerns the basic understanding of parabolic final value problems, and a large class of such problems is proved to be well posed. The clarification is obtained via explicit Hilbert spaces that characterise the possible data, giving ...

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

open access: greenElectronic 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.

On parabolic final value problems and well-posedness [PDF]

open access: greenComptes Rendus. Mathématique, 2018
We prove that a large class of parabolic final value problems is well posed. This results via explicit Hilbert spaces that characterise the data yielding existence, uniqueness and stability of solutions. This data space is the graph normed domain of an unbounded operator, which represents a new compatibility condition pertinent for final value problems.

Optimal Dynamic Portfolio with Mean-CVaR Criterion [PDF]

open access: yesRisks, 2013
Value-at-risk (VaR) and conditional value-at-risk (CVaR) are popular risk measures from academic, industrial and regulatory perspectives. The problem of minimizing CVaR is theoretically known to be of a Neyman–Pearson type binary solution.

Initial-final value problems for ordinary differential equations and applicatlons to equivariant harmonic maps [PDF]

open access: bronzeJournal of the Mathematical Society of Japan, 1998
The following ordinary differential equation \[ \ddot r(t)+ \Biggl\{p{\dot f_1(t)\over f_1(t)}+ q{\dot f_2(t)\over f_2(t)}\Biggr\}\dot r(t)- \Biggl\{\mu^2 {h_1(r(t)) h_1'(r(t))\over f_1(t)^2}+ \nu^2{h_2(r(t)) h_2'(r(t))\over f_2(t)^2}\Biggr\}= 0,\;(0,\infty) \] with \(\lim_{t\to 0}(r(t))= 0\), where \(f_i\) and \(h_i\) are given functions defined on \((
