2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/179443We study the three string junctions and string networks in Type IIB string theory by explicity constructing the holomorphic embeddings of the M-theory membrane that describe such configurations. The main feature of them such as supersymmetry, charge conservation and balance of tensions are derived in a more unified manner. We calculate the energy of the string junction and show that there is no binding energy associated with the junction.16 pages, harvmac, 2 figures, references addedHigh Energy Physics - Theorytext
