The Inverse Satisfiability Problem
SIAM Journal on Computing, 1996Summary: We study the complexity of telling whether a set of bit-vectors represents the set of all satisfying truth assignments of a Boolean expression of a certain type. We show that the problem is coNP-complete when the expression is required to be in conjunctive normal form with three literals per clause (3CNF).

On an Inverse Diffusion Problem
SIAM Journal on Applied Mathematics, 1997Summary: In many applications, such as the heat conduction and hydrology, there is a need to recover the (possibly discontinuous) diffusion coefficient \(a\) from boundary measurements of solutions of a parabolic equation. The complete inverse problem is ill posed and nonlinear, so a numerical solution is quite difficult, and we linearize the problem ...

Type of inversion problem in physics: An inverse emissivity problem
Physical Review E, 2001Inversion problems have recently drawn vast amounts of attention from the physics community due to their potential widespread applications. In this Rapid Communication, a different type of inversion problem in physics is proposed: an inverse emissivity problem, which aims to determine the emissivity g(nu) by measuring only the total radiated power J(T).

Inverse Problem with Constraints
Physical Review Letters, 1973A procedure is presented for constructing a solution to the inverse problem subject to the constraint that the wave functions be prescribed at a finite number of energies.

SIAM Review, 1998
In the inverse eigenvalue problem, one has to construct a matrix with a (partially) given spectrum. The problem appears in many different forms and in many different applications. Usually the problem is constrained in the sense that the matrix \(M\) that one wants to find has to be in a certain class. For example it should be of the form \(M=A+X\) or \(

ON THE INVERSE RESONANCE PROBLEM
Journal of the London Mathematical Society, 2003A new technique is presented which gives conditions under which perturbations of certain base potentials are uniquely determined from the location of eigenvalues and resonances in the context of a Schrödinger operator on a half-line. In particular, the authors want to treat complex-valued potential as well as potentials with slower or perhaps no decay ...
