Nonlinear dynamics of the linguistic system: how fractals function in medical discourse texts (based on English-language material)

The aim of the research is to determine the fractal dimension of medical scientific texts (based on English-language material). The scientific novelty of the study lies in the fact that it is the first to examine the laws governing the integration of biological evolution mechanisms into the self-organization schemes of linguistic systems. It is established that so-called “nonlinear neural network dynamics” permeate the open linguistic system, allowing for the assertion that a fractal in language is a composite linguistic structure whose individual parts are similar to the integrity of the entire structure. As a result of the study, it was found that a fractal in language, much like a fractal in the geometry of spatial forms, is characterized by properties of self-similarity, recursion, and fractional dimension; the collective functioning of these properties testifies to the nonlinear dynamics of the linguistic system, which is subordinated to the laws of linear hierarchy. For the first time, the nonlinear dynamics of a linguistic system is investigated from the perspective of fractional dimension. It is proven that this dynamics manifests in the invariant [T-R] model, which correlates with one of the types of simple linear progression in the communicative deployment of an utterance and can be compared to the concept of a “basic pattern of utterance deployment” in terms of fractal semiotics.
