La tesi versa sobre sistemes dinàmics discrets 1-dimensionals, des d'un punt de vista combinatori i topològic. Estem interessats en les òrbites periòdiques i l'entropia topològica de les aplicacions contínues definides en arbres i grafs.El problema central és la caracterització del conjunt de períodes de totes les òrbites periòdiques d'una aplicació contínua d'un arbre en ell mateix. El teorema de Sharkovskii (1964) fou el primer resultat remarcable en aquest sentit. Aquest bonic teorema estableix que el conjunt de períodes d'una aplicació de l'interval és un segment inicial d'un ordre lineal (ordre de Sharkovskii). Recíprocament, donat qualsevol segment inicial d'aquest ordre, existeix una aplicació de l'interval que el té com a conjunt de...
