The aim of the study is to derive the formula of personal toponymic space in D. Danilov’s novel “Sasha, Hello!” based on the theory of field nuclear-peripheral relations of constituents and the expressive potential of toponymic vocabulary. The article deals with topical integrated issues of linguistics (onomastics), literature and psychology; unified terminology is concretized, the text-forming function of identifiers of geographical objects, their aesthetic resource, implemented in dystopia, is emphasized. For the first time, the definition of the synthetic notion of “personal toponymic space” is given; a large illustrative corpus is structured; statistically representative toponymic categories (classes and subclasses), cause-and-effect relations between language and behavioural manifestations of a personality are indicated. The scientific novelty of the work lies in the primary interpretation of the unstudied, from the point of view of toponym functioning, postmodern text, the concretization of the thesaurus, taking into account the precedency of projecting person-centred linguistic representations onto other paradigms. As a result, the relativity of the theory of nuclear-peripheral relations of constituents within the framework of local artistic discourse is proved.
