Una colección infinita de parejas de gráficas isoespectrales

Palabras clave: Laplaciano en gráficas, teoría espectral, eigenvalores enteros, gráficas isoespectrales


Se construye una familia infinita de parejas de gráficas isoespectrales, es decir parejas de gráficas no isomorfas cuyos laplacianos tienen los mismos eigenvalores. Las gráficas consideradas, son un caso particular de las gráficas isoespectrales con eigenvalores enteros que pueden obtenerse con el método desarrollado en Merris (1997). En este trabajo, los espectros de las gráficas son calculados de manera directa, usando métodos elementales.
