On Recovering Sturm–Liouville-Type Operators with Global Delay on Graphs from Two Spectra
We suggest a new formulation of the inverse spectral problem for second-order functional-differential operators on star-shaped graphs with global delay. The latter means that the delay, which is measured in the direction of a specific boundary vertex, called the root, propagates through the internal...
