Uniqueness of stigmatic solutions

Journal of the Optical Society of America A, 2020
We compare two analytical methods for designing stigmatic lenses that are based on very different paradigms published recently [Appl. Opt. 57, 9341 (2018)APOPAI0003-693510.1364/AO.57.009341; J. Opt. Soc. Am. A 37, 1155 (2020)JOAOD60740-323210.1364/JOSAA.392795]. In the process, we derive a third hybrid approach, which is the result of combining the two

Unique solutions

Mathematical Logic Quarterly, 2006
AbstractIt is folklore that if a continuous function on a complete metric space has approximate roots and in a uniform manner at most one root, then it actually has a root, which of course is uniquely determined. Also in Bishop's constructive mathematics with countable choice, the general setting of the present note, there is a simple method to ...

On the complexity of unique solutions

Journal of the ACM, 1982
We show that the problem of deciding whether an instance of the traveling salesman problem has a uniquely optimal solution is complete for \(\Delta^ p_ 2\).

Uniqueness of Solutions

1972
Any normal NMR spectrum for a general spin system — one which contains no symmetry or weak coupling — arises from one and only one set of parameters, if the absolute signs of the coupling constants and the labelling of nuclei are disregarded. This holds for both the isotropic case [45] and the case involving partially oriented molecules [64].
