This article proposes to analyze the production of marginal subjectivities in Diamela Eltit's Fuerzas especiales. To this end, from the theoretical approach of Felix Guattari, the material conformation that takes place between subject, space and technology will be examined. The reading proposal is to conceive Fuerzas especiales as a scriptural performance, where the word-action seeks to break with the aesthetical and conceptual homogeneity that governed canonical literature, and, from there, to open a field of experimentation that combines new corporalities, spatialities and sonorities from the margin (social and aesthetic).
