Furthermore, we discuss some results about these submersions and present a consequent non-trivial example based on this study.</p> 2023-09-14T00:00:00+00:00 Copyright (c) 2023 International Journal of Maps in Mathematics http://journalmim.com/index.php/journalMIM/article/view/135 On QTAG-modules containing proper h-purity 2023-09-29T12:16:11+00:00 Ayazul Hasan ayaz.maths@gmail.com Rafiq Uddin rafiqamt786@rediffmail.com Mohd Hanzla sheikhhanzla96@gmail.com <p><span class="fontstyle0">There are numerous problems of determining the </span><span class="fontstyle2">QTAG</span><span class="fontstyle0">-modules in which every </span><span class="fontstyle2">h</span><span class="fontstyle0">-pure submodule is isotype or the </span><span class="fontstyle2">QTAG</span><span class="fontstyle0">-modules in which every submodule is isotype.
