Executed Renaissance. She has profusely published literary criticism with a gender perspective in journals such as '''', the journal of the
National Writers' Union of Ukraine which was formerly known as

objective realism and introduced modernist trends of
subjectivity. In 1996, Ageyeva published in conjunction with multiple other authors, a textbook in two volumes, edited by , which was a
