Faddeev

 

an island in the Arctic Ocean, in the Anzhu island group of the Novosibirskie Islands. Faddeev Island has an area of 5,300 sq km and a maximum elevation of 65 m. Edged with extensive silty sandbanks, it is composed of sands, aleurolites, and clays, intruded with veins of underground ice. It abounds in thermokarst lakes (cave-in lakes) and small rivers. Moss and lichen vegetation predominates. The island was discovered in 1805 by Ia. Sannikov and named after the industrialist Faddeev, who built the first wintering quarters there. There is trapping for blue fox on the island.

Faddeev presents facsimiles of 40 of his technical papers, and introduces each section with an explanation of the context and purpose of his work in that area of mathematical physics.
Since the developments of the Faddeev (33) and the Faddeev-Yakubovsky (34) methods to solve the 3- and the 4-body Schrodinger equations, respectively, in the form of integral equations, they have been successfully applied in many regions of few body physics because of their nature to give rigorous wave functions under assumed two-body interactions.
In the present Faddeev and Faddeev-Yakubovsky calculations, we put emphasis on the derivation and detailed analysis of the wave functions.

Our results point to several experimental and theoretical situations where such structures may be relevant, ranging from defects in liquid crystals and vortices in superfluid helium to the structure-forming role of cosmic strings in the early universe," Niemi and Faddeev say.
