A modified quasi-boundary value method for a class of abstract parabolic ill-posed problems

open access: yesBoundary Value Problems, 2006
We study a final value problem for first-order abstract differential equation with positive self-adjoint unbounded operator coefficient. This problem is ill-posed.

A quasi-boundary value regularization method for the spherically symmetric backward heat conduction problem

open access: yesOpen Mathematics, 2023
In this article, we investigate a spherically symmetric backward heat conduction problem, starting from the final temperature. This problem is severely ill posed: the solution (if it exists) does not depend continuously on the final data.

A $\mathbb{Q}$--factorial complete toric variety with Picard number 2 is projective [PDF]

open access: yes, 2017
This paper is devoted to settle two still open problems, connected with the existence of ample and nef divisors on a Q-factorial complete toric variety.

Nonstandard optimal control problem: case study in an economical application of royalty problem

open access: yesIJAIN (International Journal of Advances in Intelligent Informatics), 2019
This paper's focal point is on the nonstandard Optimal Control (OC) problem. In this matter, the value of the final state variable, y(T) is said to be unknown.

Value Functions for Bolza Problems with Discontinuous Lagrangians and Hamilton-Jacobi Inequalities [PDF]

open access: yes, 2000
We investigate the value function of the Bolza problem of the Calculus of Variations $$ V (t,x)=\inf \{\int_{0}^{t} L (y(s),y'(s))ds + \phi(y(t)) : y \in W^{1,1} (0,t; R^n) ; y(0)=x \}, $$ with a lower semicontinuous Lagrangian $L$ and a final cost ...

An elliptic boundary value problem for $G_{2}$ structures [PDF]

open access: yes, 2018
We show that the $G_{2}$ holonomy equation on a manifold with boundary, with prescribed 3-form on the boundary, is elliptic. The main point is to set up a suitable linear elliptic boundary value problem. This result leads to a deformation theory.
