2) two aspects of dialogism that are absent in Bakhtin's typology: a) dialogic strategies in the structuration of the poetic discourse and its subjects on different levels of the poem (speech strategies and positioning of the speaking subjects), and; b) the decomposition of a "hard" understanding of the philosophical category of the subject and/or the sociological category of the individual depicted on the level of the "poetic plot" (via motifs and themes from the more traditional theoretical perspective, or--in terms of cognitive approaches to literature--via schemes, frames and scripts, isotopies and events).
What we sense, in the core of the isotopies, are the trends, the directions of development, the flows that compete but remain dependent on each other.
A fundamental result about the isotopic link diagrams is: Two unoriented links and are equivalent if and only if a diagram of can be transformed into a diagram of by a finite sequence of ambient isotopies of the plane and local (Reidemeister) moves of the following three types [19]:

In conclusion, I would argue that the new code of the closed form, along with the dismantling of traditional isotopies, functions like a critique of ideologies; or rather, a critique of the semantic categories that were codified and hypostatized within those isotopies.
