Using solution sets for solving boundary value problems for ordinary differential equations
Nonlinear Analysis: Theory, Methods & Applications, 1991The authors consider a differential equation of the type \(\dot x = f(t,x)\) together with the boundary condition \(x \in S\), where \(S\) is a subset of the space \(C\) of continuous functions. The existence of a solution for such a problem is deduced from the properties of the set of solutions of an associated family of problems, parameterized by an ...

An initial value problem is analyzed for an ordinary differential inclusion for the case that the differential expression is contained in the image of a maximal monotone operator [\textit{H. Brézis}, Opérateurs maximaux monotones et semi-groupes de contractions dans les espaces de Hilbert (1973; Zbl 0252.47055)].

Transversality condition and optimization of higher order ordinary differential inclusions
Optimization, 2014In the present paper, a Bolza problem of optimal control theory with a fixed time interval given by convex and nonconvex second-order differential inclusions (PH) is studied. Our main goal is to derive sufficient optimality conditions for Cauchy problem of sth-order differential inclusions. The sufficient conditions including distinctive transversality

An automated homotopy method, based on elementary estimates, is described for the computation of inclusion intervals for the first N eigenvalues of Sturm-Liouville problems with either separated or periodic boundary conditions. Interval arithmetic (with FORTRAN-SC subroutines) is used to deal with roundoff.

Summary: In this article, we shall deal with the existence theory for a self-adjoint coupled system of three nonlinear second-order ordinary differential inclusions with cyclic anti-periodic boundary conditions on an arbitrary domain. We consider convex valued as well as non-convex valued right-hand side of the given system and apply the standard fixed-

Let F be a convex-valued multifunction \(U\to Comp R^ n\), \(U\subset R\times R^ n\), measurable on \(t\in R\) and upper semicontinuous on \(y\in R^ n\). Well-known existence conditions for the differential inclusion y'\(\in F(t,y)\) contain additionally an inclusion F(t,y)\(\subset c(t)\cdot B\), B being a zero-centred unit ball, \(c(\cdot)\in L_ 1\) [

The reachable set of a control system is the set of all states attainable at a given time. These sets have many applications, but are very challenging to obtain. In my thesis, I investigated ways to decrease the cost of numerically approximating these sets and introduced an adaptive technique which decreases cost by many orders of magnitude.
