One of the important functions of every Semiotic system is its local function. In a discourse, places have various roles such as objective, acting, being, abstract, narrative and mythical. In addition they have referential, narrative, tensional, metaphorical and transcendental functions and they play a role in creation of meaning. By strengthening objective and physical aspects of place, its cognitive dimension gets strong, while by making these aspects weaker its metaphorical dimensions are strengthened. Therefore, place is transformed into space disruption. In the "The Night when Sohrab was killed", place transforms in a way in relation to acting discourse, reciprocity and their interaction; Place becomes flexible and acquires a trans-place characteristic. The main question of the research is how and by what process does transformation of place happen, and what function leads to this transformation.  The current research is on the basis of the hypothesis that place in accordance with its functions of reciprocity, interaction, and interactive action-oriented features acquires an identity and static function. The effect of such functions on place is that it leads to its flexibility in the realm of place and space and eventually it becomes an existential and transformational place, which its main output, on the one hand, is interaction of the actor and place and on the other hand, its unity and harmony with Sohrab's mythical features and universe. The purpose of this research is to study Semiotic characteristics of place and space and to analyze conditions, place transformation and conversion of place into trans-place. This research showed that different continuous locations, non-continuations, induction, whirlwinds, and transcendence play a role in this discourse, and so these places always have active, static, emotional, inductive, mythical and transcendental functions.

The prison poems of Ahmad Shamlou are significantly different from the classical form of prison literature in terms of structure, function, content, and discourse. In the present research, we have tried to study Ahmad Shamlou’s prison poems with an integrated approach using discoursal and semiotic tools. In order to interpret the function of prison as a punitive tool, we have taken Foucault’s views and to explain the relationship between power and disciplinary space and prison punishment, the issue of authority and domination has been briefly discussed based on the ideas of some sociologists and philosophers such as Max Weber and Thomas Hobbes. Lefebvre’s views on space have been used in the interpretation of prison environment. The results indicate that unlike the classical prison poets, Shamlou first discredits the punitive and disciplinary function of the prison by not admitting the charge and considering the punishment illegitimate. Second, the prison environment in Shamlou’s prison poems is a discoursal space in which the poet has tried to use the dialectical capacity of the space by successively escaping to the outside world, emptying the prison of its physical and defined identity as an enclosed space, and portraying it as a required developmental experience in the path to achieve the goal.
