Good question....I never thought about....but some key-words can eventually help us:

experimenting, galaxy, squizoanalysis... 

Thanks a lot!. G seems to use ‘The Production of Subjectivity’ but as some of you say I must see in the context of BWO. Thanks by the attach too!

Hello Francisco,

I must agree with the answer up above that D&G refuse to consider subjectivity as a static whole, it is in constant production and becoming. You can look at What is ecosophy? by Guattari, the first chapter of Anti-Oedipus, section 11 of Gary Genosko's Guattari Reader, Ian Buchanan's introduction to his A Guide to Anti-Oedipus and Brian Massumi's extensive commentary to get a better grasp of their conception of subjectivity. But it is never clear-cut.

Edit: I would add that these authors consider subjective emergence as the pressure of external conditions and forces with internal disposition, potential and self-poisitioning. As such, subjectivity is an ever-moving becoming directly linked to the redistributions of external and internal potential and conditions.
