The influence of one literature on the other is the   consequence of cultural interaction in different nations. No literary dynamics can keep itself away from the influence of other literature. When both sides of the equation interact through the cultural and literary language of the two nations, the issue will be more serious.  Since the Literature and language of Iran and Tajikistan have the same origin, then this can be a subject for a comparative study. So in this article, we will investigate similarities and differences in how to apply mythology, poetic language, its functions and its application in both quantity and quality in the poetry language of two contemporary poet from Iran and Tajikestan ( Forough Farrokhzad, Golrokhsar Safi-Ava). The main question is that how is each of these poet`s  attitude to myth, mythological themes and  their origins, and to what extent do they have used from these mythological motifs in their poems. These motifs are: God, goddesses, gods, prophets and entrepreneurs, mythological figures, historical and epic creatures, plants and animals and mythological mythology as well as certain areas.

This comparative study, based on the Slavic approach, explains the features of utopia in the poems of Sohrab Sepehri and Nazak al-Mulaakeh, two Persian and Arabic poets, and analyzed and analyzed the aspects of their sharing and differences with regard to the descriptions of the two poets at content level. The results of the research show that both the poets have taken refuge in their imaginative and poetical uranium to escape the reality of their community; and because of their romantic tendencies and similar social conditions, they have both common themes such as escape from poverty and The cruelty and attention is given to the world of childhood, nature and the countryside. But the different tendencies and experiences of the two poets have brought the utopian utopia closer to reality, giving it a national and socio-ethical dimension, and made Sohrab utopia more cryptic, mystical, moral, and transnational and global.

This article explains the common themes of Shahriar and Fowzi Maalouf's poems by asking what common themes of their poems about nature were. To answer this question, in the research process, a descriptive analytical method has been used based on library studies and content analysis of the data. The findings of this research indicate that Shahriyar has given some reflection on the nature of the Fowzi due to a periodic crossing of his life in relation to romantic tendencies in nature. Shahriyar's attitude toward nature is the result of his own experiences and personal acquisitions, while in Fowzi's view, nature is the source of inspiration for many concepts. The characterization of nature is more realistic in the sense that the Fowzi's poetry takes on the utopianism.

Existentialism is one of the most important contemporary philosophical currents, widely reflected in literature; situation, Boundary Situations and death are major existential concepts. In this paper, the reflection of the above concepts in the poems of Shams Langeroodi was surveyed. The results and numerous examples show that firstly, these concepts were reflected to a great extent in the studied poems; secondly, these concepts were reflected through artistic logic and poetic arrangements; and thirdly, some approaches and subdivisions can be seen among the results. Four existentialist approaches to death can be seen among the poems, which are, in order of frequency, as follows: 1. Death as a phenomenon that causes decay, ending, and termination 2. Death as a fact and as a boundary situation. 3. Death and anxiety 4. Death and absurdity and futility. Among Boundary situations, suffering is the most significant. The poet has reflected on the concepts from a variety of perspectives, and therefore the existentialist approach of the poems cannot be fully traced back to a particular thinker.
Extended Abstract
Introduction
The philosophy of existentialism is a philosophy of life and deals with serious and decisive, not abstract and distant issues. As a result, these concepts have found wide acceptance in art, literature, and poetry. Concepts such as situation, boundary situations, and death are found primarily in the works of thinkers from this field. The attention to objective themes may be one of the reasons for the popularity and popularity of this movement. It seems that contemporary literary works, which are called successful works, contain these concepts in some parts. And in contemporary Iranian literature and poetry, a considerable number of creative works had (and have) significant existentialist concerns, and under certain conditions, one can see the reflection of existential considerations in their works. Existentialism in Shams Langeroodi's poems and, of course, existential death, situation and boundary situations in his poems have not been studied yet.
Theoretical Framework and Methodology
The purpose of this article was to examine the reflections of the above existential concepts in the poems of Shams Langeroodi. Therefore, the concepts of death, situation and boundary situations in the works of the most important thinkers of the philosophy of existentialism were first examined, and then the presence of these concepts in the above poems and the poet's main approaches to this concept were studied through examples. It seems that these concepts are among the most common existentialist concepts of the aforementioned poets and show considerable diversity. Due to the attention that thinkers such as Heidegger, Sartre, and Jaspers paid to the mentioned concepts, their works were examined in order to establish a framework for the analysis of the poems.
Findings, Discussion and Conclusion
The results show that all these three existential concepts are frequent in Shams Langeroodi's poems. The concept of death has been reflected in detail in four existential approaches: 1. dissolving, terminating and annihilating death 2. death, a reality and a boundry situation 3. death and sorrow 4. death, futility and despair. As for the number of poems, there are relatively many examples of terminating and annihilating death. As for the boundry situations, besides death, the boundry situation of suffering is reflected most often. The diversity of the poet's existential approaches to these three concepts is one of the obvious findings of this study. His poems reflect the many existential tendencies to which he is exposed, and, of course, he has always kept in mind that he is a poet and that his work is different from philosophizing; therefore, his poetry contains a number of existentialist theories in which the concepts of the main existentialist thinkers are reflected. Therefore, his poetry cannot be completely attributed to a particular philosopher, and, of course, the poet's emphasis in the poems under study is on "being a poem".
