NP-complete decision problems. We note that inverse complexity has consequences for another task involving computationally difficult problems – the task of generating multiple solutions 1 In fact, there are infinitely many. to a search problem, which is of both theoretical and practical interest...

The remedy against ill-posedness isregularization:To obtain stable solutions of inverse problems one constructs a family of continuous operators\(R_{\alpha }:\mathbb {Y}\rightarrow \mathbb {X}\)parameterized by a parameter\(\alpha >0\)converging pointwise to the discontinuous inverse\(F^{-1}...
Green’s functionSpectral radiusThis paper is concerned with the existence of solutions of an inverse discrete problem with sign-changing nonlinearity. This kind of problems includes, as a particular case, nth order difference equations coupled with suitable conditions on the boundary of the interval ...

We present a new regularization method for the solution of the Fredholm integral equation (FIE) of the first kind, in which we incorporate solutions corresponding to a range of Tikhonov regularizers into the end result. This method identifies solutions within a much larger function space, spanned...

Methods of first-order approximation provide solutions to the inverse scattering problems in order to get the first model using minimum a priori information about the system. To check that model, the scattering problem has to be solved. The resulting theoretical model of the function can be then...
