Upper bound for the diameter of a tree in the quantum graph theory
UDC 519.177We study two Sturm – Liouville spectral problems on an equilateral tree with continuity and Kirchhoff conditions at internal vertices and Neumann conditions at pendant vertices (first problem) and with Dirichlet conditions at pendant vertices (second problem). The spectrum of each of thes...
