An inverse problem for evolution inclusions

open access: yesAbstract and Applied Analysis, 2002
An inverse problem, the determination of the shape and a convective coefficient on a part of the boundary from partial measurements of the solution, is studied using 2-person optimal control techniques.

Row stochastic inverse eigenvalue problem

open access: yesJournal of Inequalities and Applications, 2011
In this paper, we give sufficient conditions or realizability criteria for the existence of a row stochastic matrix with a given spectrum Λ = {λ1, ..., λn} = Λ1 ∪ ⋯ ∪ Λm ∪ Λm+1, m > 0; where (pk ...

The Diagonalizable Nonnegative Inverse Eigenvalue Problem

open access: yesSpecial Matrices, 2018
In this articlewe provide some lists of real numberswhich can be realized as the spectra of nonnegative diagonalizable matrices but which are not the spectra of nonnegative symmetric matrices.

Stability of solutions for some inverse problems

open access: yesElectronic Journal of Differential Equations, 2012
In this article we establish three stability results for some inverse problems. More precisely we consider the following boundary value problem: $Delta u + lambda u + mu = 0$ in $Omega$, $u = 0$ on $partialOmega$, where $lambda$ and $mu$ are real ...

The inverse Banzhaf problem [PDF]

open access: yesSocial Choice and Welfare, 2009
Let \({\mathcal{F}}\) be a family of subsets of the ground set [n] = {1, 2, . . . , n}. For each \({i \in [n]}\) we let \({p(\mathcal{F},i)}\) be the number of pairs of subsets that differ in the element i and exactly one of them is in \({\mathcal{F}}\). We interpret \({p(\mathcal{F},i)}\) as the influence of that element. The normalized Banzhaf vector

Inverse nodal problems

open access: yesJournal of Physics A: Mathematical and Theoretical, 2009
It is shown that nodal sequences determine the underlying manifold up to scaling within classes of rectangles with Dirichlet boundary conditions, separable two dimensional tori, two-dimensional flat Klein bottles and flat tori in two and three dimensions.

Feynman's Inverse Problem

open access: yesSIAM Review
We analyse an inverse problem for water waves posed by Richard Feynman in the BBC documentary Fun to Imagine. The problem can be modelled as an inverse Cauchy problem for gravity-capillary waves on a bounded domain. We do a detailed analysis of the Cauchy problem and give a uniqueness proof for the inverse problem.
