Resolución de problemas autoadjuntos sobre redes finitas

Sea Γ = (V,E, c) una red finita, donde V es el conjunto de vértices, E es el conjunto de ramas y c : V × V −→ IR es la función de conductividad de la red, i.e., c(x, y) > 0 si x ∼ y, c(x, y) = 0 si x 6∼ y. Supondremos que la red es conexa, es decir, para todo par de vértices existe un camino que los une. Un área de trabajo de gran interés es el análisis y la solución de problemas de contorno en...
