How is Joyce Carol Oates version of "The Lady with the Pet Dog" postmodern literature?What are the characteritics of post modern literature?

Postmodernism, the child of
modernism having therefore many of the same characteristics though carried to new
extremes in a mood of celebration, is characterized by
fragmentation of time and character creating various
degrees of disunity and
incoherence in the (1)
literary structure and in the (2) characters personas and
lives, with both categories being marked by ambiguity and a
resultant loss of integral
meaning.

Some additional specifics of
postmodernism, characteristics shared with the parent
theory of modernism, are (1) a blurring of or a rejection
of the ideas of high and low literary subjects, diction, and themes, which means that
the common person and vernacular (or even low persons and vernacular) and the
corresponding subject matter and themes are fit for literary immortalization;
(2) the prevalence of literary reflexivity, also called
self-consciousness, about the literary process, product and intent, in other words,
comments within the narrative that indicate a conscious author who is consciously making
literary, stylistic, thematic, and narrative choices; (3)
the preference for ambiguity, as ambiguity is seen to reflect the discontinuity and
disordered nature of life.

In Joyce Carol Oates short
story, "The Lady with the Pet Dog," which is a recasting of Chekhov's famous short story
translated variously as "The Lady with the Little Dog," "The Lady with the Dog," and
"The Lady with the Pet Dog," Oates' structure does depend
on a fragmentation of time; the story comes is fits and starts, so to speak, of
discontinuity in time. This structure also adheres to the postmodernist ideology of
literary aesthetic that turns against traditional aesthetic
while embracing an aesthetic that favors a blurring of distinctions and
forms.

The central character,
Anna, shows some fragmentation of her personality in that
she is faced with a feeling of loss of self and confusing choices, with further
fragmentation demonstrated through her suicidal intents. Another point demonstrating
postmodernism in the story is that Anna's epiphany and the
story resolution embody ambiguity in that moral order is
upturned and Anna devises her own ideology and moral stance in a world and life that had
otherwise lost unity and meaning.
