Firstly we give a very basic list of definition that can be of some help in approaching this field. After that we present a brief review of the state of art for the models. © 2003 American Institute of Physics PB - American Institute of Physics T2 - Modeling of complex systems: seventh Granada lectures AV - none N1 - Proceedings of the VII Granada Seminar on Computational Physics, 2-7 September 2002, Granada, Spain SP - 17 TI - Introduction to complex networks M1 - 661 UR - http://dx.doi.org/10.1063/1.1571286 A1 - Caldarelli, Guido Y1 - 2003/// KW - PACS: 89.75.Hc Networks and genealogical trees ER -
