A 2-edge partial inverse problem for the Sturm-Liouville operators with singular potentials on a star-shaped graph
Boundary value problems for Sturm-Liouville operators with potentials from the class $W_2^{-1}$ on a star-shaped graph are considered. We assume that the potentials are known on all the edges of the graph except two, and show that the potentials on the remaining edges can be constructed by fractional parts of …
