The very short stories belong to a particular narrative space which has been experiencing a sustained growth since the middle of XX century, especially in Latin America. During the last years, many writers and anthologies around this narrative form have appeared in hispano-american book market. It`s the microfiction, a narrative that fits in a single page. Many narrative tools of these fictions arise from the short stories, from which they inherit the capacity of recreate tension. A rhythm that is translated in an internal pulse, even though resonances of other genres can be identified in these minimum stories. Microfiction´s language economy hides a ludic glance with a strong presence of humor and parody in the treatment of certain themes. Everyday situations, popular tales or hilarious versions of literature`s classics are blended with unknown perspectives of the human condition. Stories are told by apparently anonimous voices from a field of no-time and no-space inducing the awakening of senses over those things that in principle seem unexplainable. The analytical perspective that this study proposes is the recreation of the current cultural praxis trends of genre disintegration, by looking at some of its previous manifestations, its constitutive characteristics, as well as the implications of the resistance that the atomization of narrative in small fragments brings about. This thesis embraces microfiction as a fragmentary narrative, also analysing its relationship with fractal geometry throughout Ana Maria Shua, Luisa Valenzuela and Marina Colasanti`s work.
